Before we compare them, listen.

For when there is a duality of some kind, then the one can see the other… When, however, the Whole has become one's very self (ātman), then who is there for one to see and by what means? … Look—by what means can one perceive the perceiver?

The note The oldest Upaniṣad, c. 7th–6th c. BCE, pre-Buddhist. The Maitreyī dialogue appears twice in the same text in slightly different form — evidence of composite redaction. Whether it teaches identity-monism or the ritual one-ness of a hierarchical bandhu scheme is genuinely disputed; Olivelle's notes resist Śaṅkara's reading.

Form and technique arrive together here: the instruction and the dialogue are the same passage.

There is no distinction whatsoever between saṃsāra and nirvāṇa. There is no distinction whatsoever between nirvāṇa and saṃsāra. What is the limit of nirvāṇa, that is the limit of saṃsāra. There is not even the finest gap to be found between the two.

The note 2nd–3rd c. CE. This is the verse most often mistaken for mystical monism, and the Indian commentators explicitly block that reading by preserving the conventional difference. Whether Nāgārjuna is a semantic anti-realist or is making a metaphysical claim divides Siderits from Garfield.

Technique before form: the argument is the practice, and it leaves no separate poem.

A state in which 'this' and 'that' no longer find their opposites is called the hinge of the Way. When the hinge is fitted into the socket, it can respond endlessly.

The note The Inner Chapters are conventionally late 4th c. BCE; there is no manuscript witness, and the received text is Guo Xiang's c. 300 CE redaction of a longer version. The text mocks the totalizing move itself: having said the ten thousand things are one with me, we already have two.

Form first, technique after: the hinge is described before any method is given for reaching it.

First, relax and release your mind, / Neither scattered, nor concentrated, without thoughts. / While resting in this even state, at ease, / Suddenly let out a mind-shattering 'phaṭ!', / Fierce, forceful and abrupt. Amazing! / There is nothing there: transfixed in wonder…

The note Attributed to Garab Dorje as his final testament, and not attested in the Dunhuang manuscripts or the tenth-century bSam gtan mig sgron. It belongs to the later Nyingtig stratum and became famous through Patrul Rinpoche (1808–1887).

The clearest case on this page: the technique and the poem are the same object — the instruction is the verse.

When you gaze into the midst of the sky, fixed concepts of 'center' and 'boundary' will cease. / Likewise, when mind looks at mind, / Thoughts will cease and you see the nature of mind.

The note Attributed to Tilopa (trad. 988–1069) transmitting to Nāropa on the Ganges bank; the Tibetan text is in the Tengyur and no Sanskrit original survives, so the attribution is traditional rather than established. Milarepa is the more famous voice here, but no song of his carried this axis as cleanly in a translation that could be verified.

Same object again: the verse gives the gaze and the gaze is the practice.

'One should worship Śiva by becoming Śiva' is the old saying. But the devotees say, 'One should worship Śiva by becoming a devotee.' For they can recognize your essence as nondual, even when it is in bodily form.

The note Utpaladeva fl. c. 925–975, pupil of Somānanda and grand-teacher of Abhinavagupta. This is the sharpest verse in Layer 1, because it names the identity position and then declines it from inside a nondual system — the devotee holds nonduality without dissolving the relation.

Form first: the recognition is described in devotional verse long before it is systematized in the Īśvarapratyabhijñākārikā.

ਮਨ ਤੂੰ ਜੋਤਿ ਸਰੂਪੁ ਹੈ ਆਪਣਾ ਮੂਲੁ ਪਛਾਣੁ ॥
man tūṅ jot sarūp hai āpaṇā mūl pachhāṇ
“O my mind, you are the embodiment of the Divine Light — recognize your own origin.”

The note The Granth was compiled in 1604, expanded in 1706 and invested as Gurū in 1708. Whether it is best read as nondual at all is contested: it is sung poetry organized by rāg, addressed overwhelmingly in the second person to a Beloved — and yet its closing Muṇḍāvaṇī says sabh nānak brahm pasāro.

This verse sits on the seam the whole page turns on: “recognize your own origin” is recognition language, not identity language. The recipient stays a recipient.

His friend called to him, 'Who is at the door?' He answered, ''Tis thou art at the door, O charmer of hearts.' 'Now,' said the friend, 'since thou art I, come in, O myself: there is not room in the house for two I's.'

The note Rūmī 1207–1273; Nicholson's remains the only complete scholarly English translation. The story is annihilation of the separate claim, not assertion of identity — the lover is admitted precisely because he stops saying "I," and love still requires two. Chittick argues Rūmī should not be read through waḥdat al-wujūd, a category that post-dates him.

Form first, and the technique is elsewhere: the retreat manual is Ibn ʿArabī's, not Rūmī's.

“the substance of this work is nought else but a naked intent directed unto God for Himself.”

The note The Dionysian corpus was written c. 500 CE by an anonymous Syrian under an apostolic name; The Cloud is late-14th-c. Middle English, anonymous, and directly downstream of it. Dionysius never says the soul is God, and his hierarchies exist to preserve mediation — Eckhart and Cusanus pushed toward identity, Aquinas and the Palamites toward participation. The Luibheid translation of the Mystical Theology usually quoted here could only be verified second-hand, so this card uses a public-domain text that could be read directly.

Technique and form arrive in the same anonymous manual, four centuries after the theology it depends on.

“the realization that the world, and all its possible experiences, constituted a social reality, a fabric of life in which everything had the possibility of intimate knowing relationships because, ultimately everything was related.”

The note This card is prose, and deliberately so. There is no pan-Indigenous verse tradition; assembling one would flatten distinct nations into a generic voice, and much of what would read as “verse” here is ceremonial and not for publication. Mishuana Goeman's caution applies — against a general appeal to Indigenous consciousness in place of distinct tribal histories.

And this tradition is the counter-case, which the page keeps rather than resolves. Deloria's claim is that everything is related — which presupposes distinct relata and obligation between them. That is the opposite move from the collapse of seeker into sought, and Kimmerer's protocol only works if harvester and harvested remain two.
