The Upaniṣads

Tradition

Classical Indian scripture / the Vedic tradition (the common basis of the later Vedānta schools)

Main texts

Old Upaniṣads: Bṛhadāraṇyaka, Chāndogya, Taittirīya, Aitareya (early prose layer); Kaṭha, Īśā, Muṇḍaka, Śvetāśvatara, Māṇḍūkya (verse / later layer). All are T1 as the object of this archive; internal layers are marked on the cards.

Core original-text marks

ahaṃ brahmāsmi (I am brahman)｜tat tvam asi (you are that)｜neti neti (not thus, not thus)｜brahma veda brahmaiva bhavati (one who knows brahman becomes brahman)

Final six-position placement

②「Direct Seeing of the Ground」 (B, for the main line of the old Upaniṣads; the ① direction has systematic completion-layer material, and the key competing interpretation is C; the collection is internally heterogeneous, and the ritual–meditation layer and the theistic layer take no part in the main-class judgment)

“Only by knowing him does one pass beyond death; there is no other path to go” (E-35, comparative evidence from the theistic layer that does not independently carry the self–brahman main line); “Whoever among the gods awakened to this became that” (E-01); “Just so, a person who has a teacher here knows; for him the delay lasts only until he is released, and then he arrives” (E-21). At the same time the Upaniṣads stipulate the ground itself as knower and consciousness: “He is not seen but is the seer… there is no seer other than he” (E-08); “Here this person becomes self-luminous” (E-10); “Wisdom is brahman” (E-27); “Brahman is truth, knowledge, the infinite” (E-25). Overall classification ②「Direct Seeing of the Ground」 (B): the ground is originally present and originally identical; completion is directly stipulated as knowledge of this identity, and the ground itself is that knower.

Most distinctive feature: in the Upaniṣadic material, the completion condition in the ② direction and the non-dual / no-other-knowing statements in the ① direction both have reliable originals, and in some teachings they coexist within the same teaching. Yājñavalkya on one side says “those who know it become immortal” (E-13), and on the other says “When everything has become the self, then by what and whom would one see… by what would one know the knower?” (E-06), and calls this very teaching “this is immortality” (E-16).

Uddālaka on one side repeats “you are that” nine times (E-20), and on the other says “a person who has a teacher knows” (E-21). Part of this tension lies within one and the same teaching, but this may not be used to flatten the differences of authorial layer, formative layer and doctrine among the different Upaniṣads. “The ground is the knower” still requires distinguishing consciousness as an ontological attribute from the function of right cognition as a condition of liberation. (A: stated in the text; overall structure B)

Final load-bearing point: look at three layers. (1) Ground layer: being, one without a second (E-19); all is brahman (E-17); modifications are names (E-18); there is no diversity here (E-14). This layer does not wait on knowing; the deletion test passes. (2) Dismantling layer: neti neti (E-04, E-16); neither coarse nor fine (E-09); the seer of seeing cannot be seen (E-07); what is learned in the Vedas is only name (E-22); not obtained by exposition, intelligence or much learning (E-28); speech and mind turn back (E-26). (3) Completion layer: the knower becomes immortal (E-13); knowing brahman is becoming brahman (E-34); one who has a teacher knows and is released (E-21); one who sees diversity goes round in rebirth (E-14, E-29); at the same time, in completion there is no knower and known (E-06, E-23). The inference to ② depends on the first half of the third layer; the competition from ① depends on its second half.

Most delicate point: Bṛhadāraṇyaka 2.4.14 (E-06) and 4.5.15 (E-16). Yājñavalkya says: in the state of completion no one knows another, and the knower cannot be known; then he says “You have been instructed; this is immortality”. ① can say: completion is the disappearance of knower and known, knowing itself is cancelled, and “immortality” is simply that unknowable knower being originally so. This archive’s judgment: what is cancelled is the dual knowing of “one knowing another”, not the “knower” itself as the ground (E-08, “there is no seer other than he”); and this state is conditioned on “when everything has become the self” (past tense), while “this is immortality” confirms a single instruction. Therefore the ① reading is kept at C.

Note on texts: the Upaniṣads are not one book, nor the thought of one person. The old Upaniṣads were transmitted separately in the various Vedic schools, and their composition spans several centuries (common view: the early prose Upaniṣads around the middle of the first millennium BCE, the verse Upaniṣads later; this archive has not dated them). Even a single Upaniṣad contains heterogeneous content: ritual interpretation, meditation (upāsanā), cosmogony, doctrines of the paths after death, and teachings about the self. This archive takes the main line of “teaching about the self and brahman” as its object, and its judgment applies only to this main line;

E-35, in the theistic context of the Śvetāśvatara, is explicitly excluded from load-bearing for the main class, and may not be used to fill back the placement of the whole collection merely because it shares the “only by knowing” pattern; the entry is kept in full as a comparison. Early prose, later verse, ritual meditation and theism constitute internal differences of layer; T1 means that these texts really belong to the scope of the old Upaniṣads under examination, not that their authors or dates are wholly homogeneous.

Text levels in this archive:

• T1 (early prose layer) = Bṛhadāraṇyaka Upaniṣad (E-01—E-11, E-15, E-16); Chāndogya Upaniṣad (E-17—E-24); Taittirīya Upaniṣad (E-25, E-26); Aitareya Upaniṣad (E-27).
• T1 (verse / later layer) = the verses quoted in Bṛhadāraṇyaka 4.4 (E-12—E-14); Kaṭha Upaniṣad (E-28—E-31); Īśā Upaniṣad (E-32); Māṇḍūkya Upaniṣad (E-33); Muṇḍaka Upaniṣad (E-34); Śvetāśvatara Upaniṣad (E-35).
• T2—T3 = none (late minor Upaniṣads such as the Muktikā are not used in this archive).
• T4 = later commentaries by Śaṅkara and others: not used as evidence in this archive, mentioned only once, on card E-21.

• Evidence lacking: no cards have been made for the Kauṣītaki, Kena or Praśna Upaniṣad; modern research on dating the old Upaniṣads has not been checked; the printed editions on which GRETIL is based (the Limaye–Vadekar edition, Olivelle’s edition and others) have not been checked in the original books.

Editions and transcriptions: the Bṛhadāraṇyaka, Chāndogya, Kaṭha, Īśā, Māṇḍūkya, Śvetāśvatara and Aitareya follow the critical texts in GRETIL (transliterated into Devanagari via sanskrit/raw_etexts), located by the chapter and verse numbers marked in GRETIL; the GRETIL texts write sandhi separated (e.g. “तत् त्वम् असि”), and quotations reproduce this. The Taittirīya follows the electronic transcription in ebhAratI-sampat of the 1923 Madras edition with Śaṅkara’s commentary (English translation by S. Sitarama Sastri), and the Muṇḍaka follows the electronic transcription of a teaching edition in ebhAratI-sampat; both write sandhi joined, and are located by chapter, section and the line numbers of that electronic text.

Method: following v1.3, three questions are separated: (a) whether the ground holds without waiting on knowing — being, one without a second; all is brahman; modifications are names: yes;

2. Ground: being, one without a second (E-19); all is brahman (E-17); the imperishable (E-09); there is no diversity here (E-14).
3. The ground is the self: I am brahman (E-01); you are that (E-20); one should meditate on it only as the self (E-03); the definition of the self (E-24).
4. The ground is the knower: the seer of seeing cannot be seen (E-07); not seen but the seer (E-08); self-luminous (E-10); wisdom is brahman (E-27); truth, knowledge, the infinite (E-25).
5. Self-reflexivity of speech: neti neti (E-04, E-16); what is learned in the Vedas is only name (E-22); speech and mind turn back (E-26); not obtained by speech or mind (E-30); not obtained by exposition (E-28).
6. Knowing and not knowing: the knower becomes everything, the worshipper of other gods does not know (E-02); one who sees diversity goes from death to death (E-14, E-29); knowing the self, one has nothing to seek (E-12).
7. Completion: the knower becomes immortal (E-13); knowing brahman is becoming brahman (E-34); only knowing is the path (E-35); one who has a teacher knows and is released (E-21); the knower of the self crosses beyond sorrow (E-22); for one who discerns there is no delusion and no sorrow (E-32);

With the later verses E-13 and E-34 and the theistic comparison E-35 stripped away, ② still has independent positive evidence in the early prose, but the strength of the claim that these texts form one shared structure of completion is lower than that of judgments within each individual text. Therefore the main placement ② (B) applies only to the structural synthesis of the selected main line, and the unity of the collection as a whole and the competition from ① both remain C.

Two different kinds of knowing: the first half of E-01, brahman “knowing itself and becoming everything”, means that brahman’s self-awareness can be narrated as a mode of generation; so it should be stated precisely as “the existence of brahman does not depend on another, external knower”, not “all of brahman’s self-aware activity can be removed”. Wisdom / the knower as the highest nature (E-08, E-25, E-27) and knowing as the recognition of the self / brahman (E-01, E-13, E-21, E-34) are not the same function in the deletion test; what is deleted is the latter, and the former cannot be taken directly as proof of the ② function of completion.

State of completion and condition of completion: E-06 and E-16 dismantle objectifying cognition once non-duality has already obtained, and do not explicitly say that recognizing the self can be deleted from the complete transformation of one who does not yet know;

E-13, E-21 and E-34 positively establish the conditional relation “knowing — immortality / becoming brahman”. Hence ② does not require a permanent objectifying act of “knowing” after completion, but must still account for the function that the occurrence of right recognition has in the complete narrative of completion. The nine-fold instruction of E-20 belongs to the teaching procedure: it neither makes “you are that” merely a path, nor makes the repetition itself an ultimate condition.

Deletion test: from the complete structure, delete only the function of “knowing” (knowing “I am brahman”, those who know it are immortal, the knower of brahman becomes brahman, only knowing is the path, one who has a teacher knows), keeping being, one without a second, all is brahman, the self is brahman, the ground is the knower, and keeping virtue and release from desire as controls. Check separately which layer breaks: the stipulation of the ground, “becoming brahman”, immortality, liberation. One may not declare knowing cancelled because “when everything has become the self, by what would one know what” (E-06), nor ignore the Upaniṣadic positive stipulation of original identity in “you are that” because “the knower becomes immortal”.

(1) The ground holds: being, one without a second (E-19); all is brahman (E-17); you are that (E-20). With knowing deleted, these stipulations do not change by a single word. The first-layer deletion passes;

these are substantive positive evidence in the ① direction. (A: stated in the text)

(2) Dismantling and the learner: objectifying determination is dismantled (E-04, E-09); the seer as an object is dismantled (E-07); Vedic knowledge is reduced to name (E-22); exposition, intelligence and much learning as means of obtaining are dismantled (E-28); speech and mind are dismantled (E-26, E-30); dual worship is dismantled (E-02). What can be deleted is objectifying knowing, the knowing of verbal teaching and dual worship; the Upaniṣads themselves have already deleted them. But several teachings about the self / brahman still explicitly link “knowing” with immortality or becoming brahman (E-01, E-13, E-34); E-35’s “only path” belongs to the theistic context of the Śvetāśvatara, serves only as a comparison, and cannot be transferred to the whole collection as a unified exclusive proposition.

(3) Ultimate completion: the Upaniṣads give the same structure in many places: “We have come to know it while still here in this life; if not, great is the destruction; those who know it become immortal, the others go only to sorrow” (E-13); “Whoever knows that highest brahman becomes brahman” (E-34); “Only by knowing him does one pass beyond death; there is no other path to go” (E-35, comparison from the theistic layer); “Whoever among the gods awakened to this became that” (E-01); “Whoever thus knows ‘I am brahman’ becomes this all” (E-02);

“A person who has a teacher knows; for him the delay lasts only until he is released” (E-21); “The knower of brahman attains the highest” (E-25); “The knower of the self crosses beyond sorrow” (E-22).

Judgment and break points: removing knowing while keeping the ground, the first layer is still complete: the original identity of being and the self is unaffected. But “becoming brahman” loses its condition (E-34); the dividing line between immortality and sorrow disappears, leaving only “the others go only to sorrow” (E-13); the Śvetāśvatara’s doctrine of the single path no longer holds (E-35, limited to the context of that text); in the Gandhāra image, the “knowing” after the blindfold is removed is deleted, and the person is still in the wilderness (E-21). “Necessary” here is not what is necessary for the ground to hold, but what is necessary for immortality and liberation to hold. The B-grade break lies in the completion layer, not in the ground layer.

Test of the controls: if only virtue and release from desire are deleted while knowing is kept, the Upaniṣads say “when all the desires dwelling in the heart are released… one attains brahman here in this world” (E-31) and “one who knows thus, calm, restrained… sees the self in the self” (E-15): virtue and freedom from desire likewise bear load. But in the Upaniṣadic order, freedom from desire is mostly stipulated as the result of knowing (“if a person discerns the self…

what could he seek”, E-12) or as its accompaniment (in E-15, “one who knows thus” comes first), while “only knowing is the path” (E-35) is exclusive. Cognition is the primary bearer in the completion layer.

Path / turn / end: under v1.3, sayings of the type “those who do not know remain deluded” only show that cognition is a turn. E-14 and E-29 “whoever sees diversity goes from death to death”, E-02 “the worshipper of other gods does not know” and E-12 “if one knows the self one has nothing to seek” belong to the “turn”. What makes ② hold are the sentences at the level of “end”: “Whoever knows that highest brahman becomes brahman” (E-34) — knowing and becoming directly linked; “Only by knowing him does one pass beyond death; there is no other path to go” (E-35) constitutes an exclusive stipulation only in the context of the person / theism of the Śvetāśvatara, and cannot be directly generalized to the whole heterogeneous collection; “those who know it become immortal” (E-13); “wisdom is brahman” (E-27) — the ground itself is stipulated as wisdom, so “knowing brahman” and “being brahman” are structurally inseparable. On the other hand, E-06 and E-23 describe completion as without knower and known, and E-11 “being brahman already, he goes into brahman” and E-20 “you are that” speak of identity as originally so — these are ①-direction statements at the level of “end”.

The two ways of speaking coexist in the same body of texts and are handled by the rule for ambiguity.

The Upaniṣads’ answer to the deletion test — there are both directions: “When everything has become the self, then by what would one see… by what would one know the knower” (E-06), “where one sees no other, hears no other, knows no other, that is the vast” (E-23) and “being brahman already, he goes into brahman” (E-11) are the ①-direction answer to “with knower and known deleted, does completion still hold?”: it holds, and completion is precisely the disappearance of knower and known. “Those who know it become immortal; the others go only to sorrow” (E-13), “only by knowing him does one pass beyond death” (E-35, theistic layer) and “whoever knows that highest brahman becomes brahman” (E-34) are the ②-direction answer to “with knowing deleted, does completion still hold?”: it does not. The ①-direction sentences negate the dual activity of “one knowing another” and do not negate “the knower” — E-06 itself says that “the knower” cannot be known, and E-08 says “there is no knower other than he”. Under the supplementary rule for “judgment B”, the texts on one side say that in completion there is no knower and known and that one is originally brahman, and on the other tie immortality and becoming brahman directly to knowing; the two ways of speaking coexist, and by the ① / ② ambiguity rule the judgment is ②.

Independence of evidence and limits: the load-bearing material in the ② direction is distributed over the early prose layer (E-01, E-02, E-21, E-22, E-25) and the verse / later layer (E-13, E-34; E-35 only as comparison) of several Upaniṣads, from different teachers and lines of transmission — Yājñavalkya, Uddālaka, Sanatkumāra, the Brahmānanda vallī, Yama; the ①-direction material is concentrated mainly in Yājñavalkya’s dialogues in the Bṛhadāraṇyaka (E-06, E-11, E-16), chapters six and seven of the Chāndogya (E-20, E-23), and the Māṇḍūkya (E-33). All quotations follow electronic transcriptions only; images of the original books have not been checked; the sources of the transcriptions for E-25, E-26 and E-34 are weaker. B does not rest on the quantity of evidence, but on “knowing” consistently appearing, across different Upaniṣads and different teachers, in the position of immortality and becoming brahman.

Systematic positive evidence for the ① direction and the deletion test: the strongest version of ① is: “Being, one without a second; you are originally that; in completion everything has become the self, no one knows another, the knower cannot be known; being brahman already, one goes into brahman; the self is not obtained by exposition, only the one it chooses obtains it.

So-called ‘knowing’ is therefore only the manifestation of original identity, and in completion even knowing disappears.” This archive accepts the first four items as descriptions of the ground layer and the state of completion. But the Upaniṣads do not say that those who do not know have already become immortal; what they say is “if not, great is the destruction” (E-13). And ontological stipulations such as seer / knower / wisdom (E-08, E-27) are not the same function as the completing event of “rightly cognizing the ground”; whether the latter is still non-deletable must be decided by reading the complete chain of conditions in E-01, E-13 and E-34 against E-06, E-16 and E-23.

What has been withdrawn or de-substantialized: the objectified ground (E-04, E-09); the seer as an object (E-07); Vedic knowledge (E-22); exposition and erudition (E-28); speech and mind (E-26, E-30); dual worship (E-02); diversity (E-14); knower and known in completion (E-06, E-23).

Final load-bearing point: being, one without a second, and “you are that” are the Upaniṣads’ strongest stipulations of the ground; but across different sections and different teachers the Upaniṣads consistently stipulate immortality, liberation and “becoming brahman” by “knowing”, and stipulate the ground itself as seer, knower and wisdom — this structure of completion, conditioned on knowing while knowing is a name of the ground, is the final load-bearing point.

veda, vijñāna and the like can, in specific contexts, denote “the one who knows” and the condition of realization. One may not assume that “brahman is knowledge / wisdom” and “knowing brahman one attains completion” are the same proposition. The transcriptions of E-25, E-26 and E-34 retain the source limitations of electronic transcription and unchecked printed editions, and cannot be called a word-for-word critical edition of all transmitted texts.

Self-reflexivity: holds, and quite thoroughly. (1) Toward determinations: neti neti — there is nothing higher beyond “not thus” (E-04, E-16). (2) Toward Vedic teaching: all that is learned is only name (E-22); the self is not obtained by exposition, intelligence or much learning (E-28). (3) Toward speech and mind: speech and mind turn back, not having reached it (E-26); it cannot be obtained by speech, mind or eye (E-30). (4) Toward knowing itself: the knower cannot be known (E-06, E-07).

Self-inclusion: partly holds. The Upaniṣads give cognition a positive and fundamental place: the ground itself is seer, knower, wisdom, self-luminous (E-08, E-10, E-27); “that by which one discerns all this” (E-06) is the self. In this sense cognition is not an activity added to the ground but the ground itself. The limit is that instruction and speech themselves (“you have been instructed”, E-16; “a person who has a teacher knows”, E-21) are stipulated as means leading to knowing, not as an occurrence of the ground;

the self is obtained only by the one it chooses (E-28); in the fourth even aware and unaware are negated (E-33). If these are the ultimate meaning of the Upaniṣads, are “those who know it become immortal” and “only knowing is the path” merely teaching language for those who do not yet know?

Why it looks like ①:

• (1) Ground layer: being, one without a second (E-19); all is brahman (E-17); there is no diversity here (E-14).
• (2) Original identity: you are that (E-20); I am brahman (E-01); being brahman already (E-11).
• (3) No knower and known in completion: by what would one know what (E-06); the vast (E-23).
• (4) Obtaining does not come from the subject: only the one it chooses (E-28).
• (5) Beyond awareness: the fourth (E-33).

Taken together these five layers form a fairly complete ①-direction candidate, which must be taken seriously.

Why it is still ②:

• (1) The dividing line of knowing and immortality: “Those who know it become immortal; the others go only to sorrow” (E-13).

• (2) Knowing and becoming brahman: “Whoever knows that highest brahman becomes brahman” (E-34).
• (3) The exclusivity of knowing: “Only by knowing him does one pass beyond death; there is no other path to go” (E-35).
• (4) Awakening and becoming: “Whoever among the gods awakened to this became that” (E-01); “Whoever thus knows ‘I am brahman’ becomes this all” (E-02).
• (5) The teacher and liberation: “A person who has a teacher knows; for him the delay lasts only until he is released” (E-21).
• (6) The ground is the knower: “There is no seer other than he” (E-08); “Wisdom is brahman” (E-27).
• (7) Deletion test: delete knowing while keeping the ground, and the dividing line between immortality and sorrow disappears and the only path is deleted.

Source level and terminological boundary: the key materials for both the ① and the ② direction are in T1, and coexist in the same Bṛhadāraṇyaka and in the teaching of the same Yājñavalkya; neither side depends on weaker texts. “Knowing (veda)” and “awakening (pratyabudhyata)” are the Upaniṣads’ own terms;

Why it cannot yet be placed at ①: the positive evidence includes “being, one without a second”, “you are that”, the non-objectifiability of the seer and the finitude of instruction itself (E-06, E-16, E-20, E-23), but whether these constitute systematic self-inclusion for the whole selected group of texts remains disputed; and E-01, E-13 and E-34 mean that the completion condition of rightly cognizing the self / brahman cannot be lightly deleted. ① would need to prove both that cognition (including the speech and understanding of thought itself) is positively built in, and that the complete ultimate structure still holds once the function of rightly cognizing the ground is deleted. The “awareness is the ground” of E-08 / E-27 is only an ontological stipulation that needs examination, and cannot directly replace the deletion test.

Why not ③: the Upaniṣads do contain much inquiry (“what is that, by knowing which everything is known?”, in the context of E-18; “what is the self that is within all?”, in the context of E-07), but the answer to the inquiry is pointed out directly (“you are that”, “this is your self”), and its endpoint is knowing and immortality, not the inquiry itself.

Why not ④: the Upaniṣads have cosmogony and doctrines of the paths after death, but the endpoint of their main line is knowing the self, not the explanation of the world.
