We Were Taught Life Has Four Stages. The Oldest Law Books Argued Over Them as Choices — and One Quotes a Saying That an Asura Invented Them

Pataliputra, around 300 BCE: a Greek counts thirty-seven years

Let me take you somewhere first.

Pataliputra. The capital of Chandragupta Maurya, under modern Patna. A Greek has come up the royal road as an ambassador. His name is Megasthenes. When exactly? Nobody knows. E. A. Schwanbeck, the German scholar who collected his fragments, put the journey somewhere between 302 and 288 BCE, in the passage J. W. McCrindle translated in 1877. (McCrindle 1877, p. 16) So, around 300 BCE.

His own book is lost. What survives are pieces quoted by later Greek writers. And one of those pieces, kept by the geographer Strabo, describes the Brahmins.

Listen to what he saw. "The philosophers have their abode in a grove in front of the city within a moderate-sized enclosure. They live in a simple style, and lie on beds of rushes or (deer) skins." They listen to serious talk. And the student? "The hearer is not allowed to speak, or even to cough, and much less to spit." (Strabo XV.1.59, in McCrindle 1877, p. 99)

Not even cough. Imagine sitting through that for one afternoon.

Now the line that made me sit up. "After living in this manner for seven-and-thirty years, each individual retires to his own property, where he lives for the rest of his days in ease and security." "They marry as many wives as they please, with a view to have numerous children." (pp. 99–100)

Thirty-seven years of study. Then home, marriage, children and comfort, "for the rest of his days".

Think about what is missing. There is no forest at fifty. No renouncer at seventy-five. A Greek visitor watched the Brahmins of the Mauryan capital and saw two lives: student, then householder.

But he did see forest people. In the same passage he describes another class of thinkers, the Sarmanes, and says the most honoured of them are called the Hylobioi, the "forest-livers". "They live in the woods, where they subsist on leaves of trees and wild fruits, and wear garments made from the bark of trees." Kings consult them by messenger. (Strabo XV.1.60, McCrindle pp. 101–102) But in his account, they are a separate class of people. Not grandfathers who used to run a household.

Hold that picture. Because the one most of us carry is different: a ladder of four steps, climbed in order. Student, householder, forest, renouncer. I opened the oldest law books that name the four to see where that ladder came from. What I found is a better story.

Seven numbers to hold before we start

Keep these seven in your pocket.

• 37 years. Megasthenes' figure for Brahmin study before marriage, around 300 BCE. (Strabo XV.1.59, McCrindle 1877, p. 99)
• 4 orders, householder named first. "There are four orders, viz. the householdership, the studentship, the order of ascetics, and the order of hermits in the woods." (Āpastamba Dharmasūtra 2.9.21.1; Bühler, SBE 2, 1879, p. 151)
• 1 order only. Gautama and Baudhāyana both report that "the venerable teacher" allowed one way of life, the householder's. (Gautama 3.36, SBE 2 p. 193; Baudhāyana 2.6.11.27, SBE 14 p. 260)
• 80,000 sages, twice. Those who wanted children got burial-grounds; those who did not got immortality, in two verses Āpastamba quotes. (Āpastamba 2.9.23.4–5, SBE 2 pp. 156–157)
• 36 years. Manu's longest term for Vedic study: thirty-six years, "or for half that time, or for a quarter". (Manu 3.1; Bühler, SBE 25, 1886, pp. 74–75)
• 3 debts. Manu says a man who seeks liberation before paying his three debts "sinks downwards". (Manu 6.35, SBE 25 p. 205)
• "The fourth part" of life. The law book that fixes the four in one order across one man's whole life is Manu, chapter 6. (Manu 6.33, SBE 25 pp. 204–205)

Study, choice, refusal, a verse about children and immortality, then the ladder and its price. That is the whole journey.

First, the words a beginner needs

A few words before we open the books.

Āśrama (आश्रम). Today, one of the four "stages of life". It also means a hermitage. The root is śram, "to exert oneself", especially in austerity. (Monier-Williams, Sanskrit-English Dictionary, pp. 158, 1096) Bühler translates it "order". I say "way of life" or "order", because "stage" is the very thing in question.

Brahmacarya (ब्रह्मचर्य). The life of a celibate Vedic student. In plain English: the student.

Gṛhastha (गृहस्थ). The householder: married, earning, keeping the household fires, raising children.

Vānaprastha (वानप्रस्थ). The forest-dweller or hermit. He lives in the woods on what grows wild.

Saṃnyāsa (संन्यास). Renunciation: giving up home, fire and property to wander and beg. The person is a renouncer (the texts also say parivrājaka, "wanderer", or bhikṣu, "beggar"). In plain English: the renouncer.

Dharmasūtra. A book of short rules on right conduct. Four survive under the names of Āpastamba, Gautama, Baudhāyana and Vasiṣṭha. Georg Bühler translated them into English in 1879 and 1882.

Manu (the Mānava Dharmaśāstra). A later, longer law book in verse. Bühler thought it was composed between the second century BCE and the second century CE. (SBE 25, Introduction, p. cxvii)

Twice-born. A man of the three upper varnas who has had the sacred-thread initiation. Be clear on this from the start: these rules are written for twice-born men. Women appear in them mostly as wives.

Snātaka. "One who has bathed": the graduate, after the ritual bath that ends Vedic study.

Upanishad. Philosophical texts attached to the Veda, some old, some much later. We open three.

The claim we are testing

Here is the version most of us carry around: "Hindu tradition divides a man's life into four stages: student until about 25, householder until 50, forest-dweller until 75, renouncer after that. Everyone was meant to pass through them in order. This is the ancient scheme."

I like that version. It gives every age a job. So I broke it into four claims and tested each.

1. There are four āśramas, and they are ancient. True. All four Dharmasūtras name the same four. (Āpastamba 2.9.21.1; Gautama 3.2; Baudhāyana 2.6.11.12; Vasiṣṭha 7.1–2)
2. They were always meant to be lived one after another. Unsupported for the oldest texts. Vasiṣṭha says the graduate may choose any one, Āpastamba says "he may perform what he wishes", and Gautama reports that "some" say so. Āpastamba has the hermit and the renouncer leave straight from studentship, "remaining chaste". A step-by-step sequence appears in Āpastamba only as the view of "some", and only for the hermit. The full ladder is laid out in Manu, chapter 6.
3. The tradition agreed that all four were good. Myth. Two Dharmasūtras record the verdict of "the venerable teacher" that there is only one order, the householder's. One of them quotes a passage saying an Asura made the divisions.
4. Each stage is 25 years. Unsupported. Manu speaks of "the fourth part" and "the third part" of life. In the Bühler translation of Manu that I read, I found no figure of 25 years for a stage. The 25-year arithmetic is a modern way of splitting a hundred-year life.

One true, two unsupported, one myth. Hold on to that score.

Before the four: three branches and men who walked away

Before anyone counted four, there were older texts that knew about all these lives. They just did not arrange them.

Open the Chāndogya Upanishad, book 2, section 23. "There are three branches of the law. Sacrifice, study, and charity are the first, Austerity the second, and to dwell as a Brahmakârin in the house of a tutor, always mortifying the body in the house of a tutor, is the third." (Chāndogya 2.23.1–2; Müller, SBE 1, 1879, p. 35)

Sacrifice and charity: the householder. Austerity: the forest. Life in the teacher's house: the permanent student. Max Müller's footnote maps them onto the āśramas like that. (SBE 1, p. 35 n. 1) But the text itself does not use the word āśrama. It does not say "first this, then that". It gives three kinds of life side by side.

Then the surprise. All three "obtain the worlds of the blessed; but the Brahmasamstha alone (he who is firmly grounded in Brahman) obtains immortality." (p. 35) The top is outside all three.

Now open the Bṛhadāraṇyaka Upanishad. Here you meet men who walk away. "When Brâhmanas know that Self, and have risen above the desire for sons, wealth, and (new) worlds, they wander about as mendicants." (Bṛhadāraṇyaka 3.5.1; Müller, SBE 15, 1884, pp. 129–130) And again: "Wishing for that world (for Brahman) only, mendicants leave their homes." "Knowing this, the people of old did not wish for offspring." (4.4.22, pp. 179–180)

Did not wish for offspring. In texts that elsewhere call a son a man's immortality, that is radical.

Then the most human scene of all. The sage Yājñavalkya says to one of his two wives: "Maitreyî, verily I am going away from this my house (into the forest). Forsooth, let me make a settlement between thee and that Kâtyâyanî (my other wife)." (Bṛhadāraṇyaka 2.4.1; SBE 15, p. 108)

A man about to leave. Doing what any of us would do. Dividing the property.

And Maitreyī answers with a question I love. "My Lord, if this whole earth, full of wealth, belonged to me, tell me, should I be immortal by it?" (2.4.2, p. 108)

She does not want the settlement. She wants what he is leaving for.

One detail. "(into the forest)" is Müller's addition. He notes that the retelling in book 4 uses pravrajiṣyan, "about to go forth", the technical word for renunciation. (p. 108 n.) Forest and renunciation sit close together, in no stated order.

So here is where things stand before the law books. Students, householders, forest ascetics and wandering renouncers all exist. What nobody has yet done is put them in one box.

"There are four orders": Āpastamba's menu, not a ladder

Let me ask you something. If you listed four ways of life, wouldn't you start with the student? That's the order a person lives them.

Āpastamba does not. Here is his sentence. "There are four orders, viz. the householdership, the studentship, the order of ascetics, and the order of hermits in the woods." (Āpastamba Dharmasūtra 2.9.21.1; Bühler, SBE 2, 1879, p. 151)

In Sanskrit it is one short line: catvāra āśramā gārhasthyam ācāryakulaṃ maunaṃ vānaprasthyam iti. (GRETIL text, 2.9.21.1) Householder first. The forest hermit last.

The commentator Haradatta asked why the author says "four" at all. His answer, in Bühler's note: so that nobody concludes that "one order only, that of the householder, should be allowed, as has been taught in other Smritis". (SBE 2, p. 151 n.) Keep that phrase, "one order only". It comes back soon.

Now read the next lines slowly.

"If he lives in all these four according to the rules (of the law), without allowing himself to be disturbed (by anything), he will obtain salvation." (2.9.21.2) Living with the teacher after initiation, Āpastamba says, is "common to all of them". So is not abandoning sacred learning. (2.9.21.3–4) And then: "Having learnt the rites (that are to be performed in each order), he may perform what he wishes." (2.9.21.5, p. 152)

He may perform what he wishes. In plain words: everyone goes to the teacher first. After that, you pick.

And now the sentence that breaks the ladder. On the renouncer: "Only after (having fulfilled) the duties of that (order of students) he shall go forth (as an ascetic), remaining chaste." (2.9.21.8, p. 152) On the forest hermit, in almost the same words: "Only after (completing) that (studentship) he shall go forth, remaining chaste." (2.9.21.19, p. 153)

Remaining chaste. Think about what that means. A man who has never married cannot be a grandfather. Āpastamba's hermit is not a retired father of grown sons. He is a young man who walked from his teacher's house into the forest and never married at all.

Bühler's note agrees, with a condition: if a man considers himself sufficiently purified by his studentship, he "may become a Samnyasin immediately after its completion"; otherwise he may first become a householder or a hermit. (p. 152 n. 8) And it is a hard life: "without a fire, without a house, without pleasures, without protection". (2.9.21.10, p. 152)

Now here is the part I find fascinating. Āpastamba knows a sequence. He just does not adopt it. And it is for the hermit only. "Now some (teachers) enjoin for the hermit the successive performance (of the acts prescribed for the four orders)." (2.9.22.6, p. 154) On that view, a man studies, marries, kindles his fires, performs the sacrifices, and only then "shall build a dwelling, and dwell outside the village with his wife, his children, and his fires, Or (he may live) alone." (2.9.22.7–9, p. 154)

"Some". A sequence is already in one of the oldest law books. But it covers only the move from householder to hermit, and it is somebody else's opinion, reported in the third person, after the author's own rule.

Then Āpastamba stages a debate on which order is best. The ascetics' side quotes two verses from a Purāṇa: "Those eighty thousand sages who desired offspring passed to the south by Aryaman's road and obtained burial-grounds. Those eighty thousand sages who desired no offspring passed by Aryaman's road to the north and obtained immortality." (2.9.23.4–5, pp. 156–157)

One road to the cremation ground, one to immortality. A sharp jab at the householder.

Āpastamba answers for the householder: the Vedas are the highest authority, and they order rites performed "(in conjunction) with a wife". (2.9.23.9, p. 157) He quotes the Veda: "In thy offspring thou art born again, that, mortal, is thy immortality." (2.9.24.1, p. 158)

And how does he end? Not with a winner. Even if some ascetic gains heaven by austerity, he says, "still this is no reason to place one order before the other." (2.9.24.15, p. 159)

Four ways of life, side by side, none ranked first.

The teacher who said: only one

So Āpastamba lists four and ranks none. Now the other three old law books. This is where it gets interesting.

Gautama begins his third chapter like this: "Some (declare, that) he (who has studied the Veda) may make his choice (which) among the orders (he is going to enter)." (Gautama 3.1; SBE 2, p. 190)

Did you catch the first word? "Some." Gautama reports the free choice as somebody's opinion.

He names the four: the student, the householder, the ascetic (bhikṣu) and the hermit in the woods (vaikhānasa). And then: "The householder is the source of these, because the others do not produce offspring." (3.2–3, p. 190)

He gives careful rules for the student, the ascetic and the hermit; the householder's own rules fill the chapters that follow. The ascetic keeps no store and enters a village only to beg. The hermit never steps on ploughed land and dresses in bark and skins. (3.11–35, pp. 191–193) Then the last line of the chapter. Listen carefully.

"But the venerable teacher (prescribes) one order only, because the order of householders is explicitly prescribed (in the Vedas)." (3.36, p. 193)

Thirty-five careful sūtras on the orders. Then one sentence saying the teacher accepts only one of them.

Haradatta's gloss, in Bühler's note, is blunter: the other orders are prescribed "only for those unfit for the (duties of" a householder. (p. 193 n. 36)

Now Baudhāyana. He also names the four: "The student, the householder, the hermit in the woods, the ascetic." (Baudhāyana 2.6.11.12; Bühler, SBE 14, 1882, p. 258) Notice: this time in the order of a life. Then the same move as Gautama. "But the venerable teacher (declares) that there is one order only, because the others do not beget offspring." (2.6.11.27, p. 260)

And then Baudhāyana goes further than anyone. "With reference to this matter they quote also (the following passage): 'There was, forsooth, an Asura, Kapila by name, the son of Prahlada. Striving with the gods, he made these divisions. A wise man should not take heed of them.'" (2.6.11.28, pp. 260–261)

Read that twice. Inside one of the four oldest law books on the subject, a quoted passage says the divisions were made by an Asura, a rival of the gods, while competing with them, and a wise man should ignore them. The tidy four stages we are taught as the heart of the tradition. Here, inside the tradition, traced to the gods' opponent.

Some teachers, he notes just before listing the four, read a Vedic verse about "four paths" as a fourfold division of duties. No, he answers: it means four kinds of sacrifice. He repeats the point straight after the Asura passage. (2.6.11.9–11, p. 258; 2.6.11.29, p. 261) And he closes with a warning: "he who praises other (duties) becomes dust and perishes." (2.6.11.34, p. 262)

Now the fourth book, Vasiṣṭha. He is the friendliest to choice. "There are four orders, Viz. (that of) the student, (that of) the householder, (that of) the hermit, and (that of) the ascetic. A man who has studied one, two, or three Vedas without violating the rules of studentship, may enter any of these (orders), whichsoever he pleases." (Vasiṣṭha 7.1–3; SBE 14, p. 40)

Whichsoever he pleases. That is a menu.

But even Vasiṣṭha has a favourite. "A householder alone performs sacrifices, a householder alone performs austerities, and (therefore) the order of householders is the most distinguished among the four." And then a beautiful image: "As all rivers, both great and small, find a resting-place in the ocean, even so men of all orders find protection with householders." (8.14–15, p. 44)

The score: four books, the same four names. Two allow a free choice. Two record a teacher who allows only one. None lays out the ladder as its own rule.

Wrinkles, white hair and a grandson: how Manu built the ladder

Now let's open Manu. And here, at last, is the picture you and I were taught.

Manu starts by fixing the student's term: thirty-six years, "or for half that time, or for a quarter, or until the (student) has perfectly learnt them". Then the graduate "shall enter the order of householders". (Manu 3.1–2; Bühler, SBE 25, 1886, pp. 74–75) Not "may choose". Shall enter.

Thirty-six years at the top end. Remember Megasthenes' thirty-seven? Close enough to make you smile.

Chapter 4 opens with the clock: "Having dwelt with a teacher during the fourth part of (a man's) life, a Brahmana shall live during the second quarter (of his existence) in his house, after he has wedded a wife." (4.1, p. 128)

Then chapter 6, the famous one. "When a householder sees his (skin) wrinkled, and (his hair) white, and the sons of his sons, then he may resort to the forest." (6.2, p. 198)

Wrinkles. White hair. Grandchildren. He is not Āpastamba's young celibate. He is your grandfather.

And he may go "either committing his wife to his sons, or accompanied by her". (6.3, p. 199) So the forest is now somewhere a married couple can retire to together.

Then the last step. "But having thus passed the third part of (a man's natural term of) life in the forest, he may live as an ascetic during the fourth part of his existence, after abandoning all attachment to worldly objects." (6.33, pp. 204–205)

Student, householder, forest, renouncer. First quarter, second quarter, third part, fourth part. There is the ladder.

But notice what Manu has to add to make the ladder work. A price.

"When he has paid the three debts, let him apply his mind to (the attainment of) final liberation; he who seeks it without having paid (his debts) sinks downwards." (6.35, p. 205) The next verse spells out what he must have done first: studied the Vedas, "begat sons according to the sacred law", and offered sacrifices. (6.36) A man who seeks liberation without them "sinks downwards". (6.37)

Do you see what happened? Āpastamba's young renouncer, straight from his teacher's house, is now a man who "sinks downwards". Renunciation has not been banned. It has been moved to the end of life, after the sons.

And Manu still keeps the old quarrel alive. Look at this: "The student, the householder, the hermit, and the ascetic, these (constitute) four separate orders, which all spring from (the order of) householders." (6.87, p. 214) Then the householder "is declared to be superior to all of them; for he supports the other three." Then Vasiṣṭha's rivers and ocean, word for word in Bühler's English. (6.89–90, pp. 214–215)

So the householder wins after all. Not by abolishing the other three, but by placing them on either side of him in time.

"On the very day": the Upanishad that kept the door open

Did the ladder simply win? Not completely.

A later text, the Jābāla Upanishad, has King Janaka of Videha ask Yājñavalkya: "Sir, tell me about renunciation." (Jābāla Upanishad 4)

And Yājñavalkya first gives the ladder, almost like a textbook. brahmacaryaṃ parisamāpya gṛhī bhavet; gṛhī bhūtvā vanī bhavet; vanī bhūtvā pravrajet. "Having completed studentship, let him become a householder. Having been a householder, let him become a forest-dweller. Having been a forest-dweller, let him go forth."

Then, in the very next breath, he takes it apart. yadi vetarathā brahmacaryād eva pravrajed gṛhād vā vanād vā. "Or else, let him go forth straight from studentship, or from the house, or from the forest."

And then the line I cannot stop thinking about. atha punar avratī vā vratī vā snātako vā 'snātako vā utsannāgniko vā yad ahar eva virajet tad ahar eva pravrajet. "And again: whether he keeps the vows or not, whether he has graduated or not, or if his household fire has gone out, on the very day he becomes free of desire, on that very day let him go forth." (Jābāla Upanishad 4; Sanskrit text as given by sanskritdocuments.org; the English renderings are mine. Patrick Olivelle published a full scholarly translation in Saṃnyāsa Upaniṣads (Oxford University Press, 1992), p. 142; his wording differs in places.)

On the very day. Not at the fourth quarter. Not after the grandsons. The day the wanting stops.

So the ladder and the open door ended up in the same paragraph. The tradition kept both.

What a scholar found when he read them all together

I am not the first to notice this. In 1993 the Sanskritist Patrick Olivelle published a whole book on it: The Āśrama System: The History and Hermeneutics of a Religious Institution (Oxford University Press). Every line of his I quote below was checked word for word against the printed book.

He opens by noting that the Brahmanical tradition sees the four as "distinct and legitimate ways of leading a religious life". (Prologue, p. 3) And he states his finding plainly: the system "originated as a theological scheme that presented four alternative paths of religious living to adult males, any one of which they may freely choose." (p. 4) On the origins, he saw what we just saw: "Gautama and Baudhayana, two of the earliest authors to record the system, present it as an opponent's position", while Āpastamba "appears to accept the legitimacy of the system, but with deep reservations." (Ch. 3, "The Origins", p. 73)

Then the turn. "In contrast to the original system, the classical formulation considers the āśramas not as alternative paths open to an adult male but as obligatory modes of life suitable for different periods of a man's life." And: "Choice, which was a central element in the original formulation, is eliminated." And: "The strictly ascetical modes of life—those of the hermit and the renouncer—are recast as institutions of old age." (Ch. 5, "The Classical Āśrama System", p. 131)

Recast as institutions of old age. That is the forest at fifty.

He also admits the ladder never quite fit real life. The classical system imposed "a somewhat artificial sequence", one "that did not totally correspond to actual practice, especially in the case of renunciation." (Ch. 6, p. 161) To me, Jābāla's "on the very day" looks like that mismatch, written into scripture. Olivelle is careful here: he says Jābāla gives a choice about when to renounce, not a choice among the āśramas, and should not be confused with the original system. (p. 119)

And the time span? He places the major developments "roughly between the fifth century B.C.E. and the fifth century C.E." (Ch. 8, p. 220)

Read the actual document

Don't take my word for any of this. Here is Gautama's third chapter, its first three rules and its last, as Bühler put them into English in 1879:

"Some (declare, that) he (who has studied the Veda) may make his choice (which) among the orders (he is going to enter). (The four orders are, that of) the student, (that of) the householder, (that of) the ascetic (bhikshu), (and that of) the hermit in the woods (vaikhânasa). The householder is the source of these, because the others do not produce offspring. … But the venerable teacher (prescribes) one order only, because the order of householders is explicitly prescribed (in the Vedas)." — Gautama Dharmasūtra 3.1–3, 3.36, in Bühler, SBE 2 (1879), pp. 190, 193

Now in plain words. The first rule reports a view: after Vedic study, you choose one of four lives. Not a sequence. One. The second names the four. The third says why the householder matters most: only he has children, so the others depend on him to exist. And the last gives the verdict of "the venerable teacher": only the householder's life is truly commanded by the Veda.

So this early form of the "four stages" is not a ladder. It is a choice, and here even the choice is reported as someone else's opinion. A live argument, written down.

The strongest case for the other side

Now the best case against my reading, from the record itself.

One: a sequence is as old as the oldest books. Āpastamba already knows "some (teachers)" who teach "the successive performance" of the orders, with the man moving outside the village with "his wife, his children, and his fires". (2.9.22.6–8, p. 154) So the ladder is not a late invention out of nowhere. Its first form, for the hermit only, is an old minority view, and a sequence later became the main one.

Two: in these books, choice was not the dominant view either. Gautama attributes the choice to "some" and Bühler's note says other law books held that a Brahmin "must pass through all the four orders". (SBE 2, p. 190 n.) So my "four choices" is itself one voice among several. Fair. What the record shows is a debate, not a settled original.

Three: Manu is the tradition's own voice. The orders "assumed successively", he says, lead to "the highest state". (6.88, p. 214) A believer can fairly call the classical form the authoritative one.

Four: the pieces were gathered early, and the ladder often comes first. The Chāndogya already gathers householder virtues, austerity and lifelong studentship as "three branches" of one law, though Müller notes that "first" there is "not the first in rank or succession". (2.23.1–2; SBE 1, p. 35 n. 1) And even Jābāla gives the ladder before it gives the exception.

All four points are real. None shows the four were first taught as compulsory stages in order. They show the order was argued for, early and often.

What we could not prove

Here is exactly where my research ran out.

• Olivelle's full argument. I quote a handful of his sentences, checked against the printed book, mostly from the opening pages of his chapters. I have not tested his whole argument chapter by chapter. (Olivelle 1993, pp. 3–4, 73, 119, 131, 161, 220)
• Exact dates of the four Dharmasūtras. I give Bühler's 1879 estimates and Olivelle's broad span. I did not open a modern dating study for each book, so I cannot tell you how later scholars revised Bühler's dates.
• The date of the Jābāla Upanishad. I read the Sanskrit and give my own rendering; Olivelle's 1992 translation exists, and I note where it differs only in wording.
• Who Megasthenes' Hylobioi were. McCrindle's notes record Schwanbeck matching them to the Sanskrit forest-dweller, and also record a dispute over whether the Sarmanes were Buddhists. (McCrindle 1877, pp. 98, 101 nn.) And we read Megasthenes only through Strabo's quotation.
• The 25-year stages. I did not find a 25-year figure for a stage in Bühler's Manu. I cannot tell you who first wrote it down.
• How many people actually lived any of this. These are rulebooks for twice-born men. They tell us what learned authors argued, not how most people, or most women, lived.

Why it still matters today

Retirement. Many of us half-believe in an ancient rule: step back when you are old and hand over. Manu says something close to it. But the older books also let a young man go straight to the forest, stay with his teacher for life, or never leave home. "The ancient way" turns out to be several ways. That gives a family more room, not less.

Duty and freedom, side by side. The householder is "the source" of the rest, because only he has children, and he "supports the other three". (Gautama 3.3; Manu 6.89) And yet Maitreyī asks whether all the wealth on earth could make her immortal. Both are in the record. If you have read our companion file on the four aims of life, you will know the pattern: dharma, artha and kama first, moksha arriving as "a fourth". The stages and the aims were both argued over, not handed down tidy.

Method. The tidy version is not wrong; Manu is a real ancient text. It is incomplete, because it is one voice presented as the only one. When someone says "the tradition says", ask: which book, which verse, and what did the book next to it say?

Verdict

So what do the documents prove?

That the four ways of life are ancient. All four Dharmasūtras name them, and the older Upanishads already know students, householders, ascetics and men who leave home.

That in the oldest law books, the four were not a ladder. Āpastamba and Vasiṣṭha let the graduate choose. Āpastamba's hermit and renouncer leave straight from the teacher's house, unmarried. A step-by-step sequence appears there only as the view of "some", and only for the hermit.

That the four were contested. Gautama and Baudhāyana each record "the venerable teacher" allowing one order only, the householder's. Baudhāyana quotes a passage blaming an Asura for the divisions.

And that the ladder you and I were taught is real and old, laid out in Manu, chapter 6: forest at grandchildren, renunciation in "the fourth part" of life, and only after three debts are paid.

What they do not prove is that the ladder was the original idea, or that each stage was twenty-five years.

If you ask me, the oldest version is the more interesting one. A graduate told: here are four lives, pick one. And a teacher in the next book saying: there is only one. That argument is the real heritage. The neat ladder is how one side tidied it up.

You decide which version you want to pass on.
