Chāndogya Upaniṣad 6.4

6.4.1

yad agne rohitaṃ rūpaṃ tejasas tad rūpam \
yac chuklaṃ tad apām \
yat kṛṣṇaṃ tad annasya \
apāgād agner agnitvam \
vācārambhaṇaṃ vikāro nāmadheyaṃ trīṇi rūpāṇīty eva satyam \\604.1\

1. Whatever red form fire has, is the form of heat; whatever white, the form of water; whatever dark, the form of food. The firehood has gone from fire: the modification is merely a verbal distinction, a name. The reality is just "the three forms."

6.4.2

yad ādityasya rohitaṃ rūpaṃ tejasas tad rūpam \
yac chuklaṃ tad apām \
yat kṛṣṇaṃ tad annasya \
apāgād ādityād ādityatvam \
vācārambhaṇaṃ vikāro nāmadheyaṃ trīṇi rūpāṇīty eva satyam \\604.2\

2. Whatever red form the sun has, is the form of heat; whatever white, the form of water; whatever dark, the form of food. The sunhood has gone from the sun: the modification is merely a verbal distinction, a name. The reality is just "the three forms."

6.4.3

yac candramaso rohitaṃ rūpaṃ tejasas tad rūpam \
yac chuklaṃ tad apām \
yat kṛṣṇaṃ tad annasya \
apāgāc candrāc candratvam \
vācārambhaṇaṃ vikāro nāmadheyaṃ trīṇi rūpāṇīty eva satyam \\604.3\

3. Whatever red form the moon has, is the form of heat; whatever white, the form of water; whatever dark, the form of food. The moonhood has gone from the moon: the modification is merely a verbal distinction, a name. The reality is just "the three forms."

6.4.4

yad vidyuto rohitaṃ rūpaṃ tejasas tad rūpam \
yac chuklaṃ tad apām \
yat kṛṣṇaṃ tad annasya \
apāgād vidyuto vidyuttvam \
vācārambhaṇaṃ vikāro nāmadheyaṃ trīṇi rūpāṇīty eva satyam \\604.4\

4. Whatever red form the lightning has, is the form of heat; whatever white, the form of water; whatever dark, the form of food. The lightninghood has gone from the lightning: the modification is merely a verbal distinction, a name. The reality is just "the three forms."

6.4.5

etad dha sma vai tadvidvāṃsa āhuḥ pūrve mahāśālā mahāśrotriyāḥ \
na no 'dya kaścanāśrutam amatam avijñātam udāhariṣyati \
iti hy ebhyo vidāṃ cakruḥ \\604.5\

5. Verily, it was just this that the great householders, greatly learned in sacred lore, knew when they said of old: "No one now will bring up to us what has not been heard of, what has not been thought of, what has not been understood." For from these [three forms] they knew [everything].

6.4.6

yad u rohitam ivābhūd iti (S ) iti tad vidāṃ cakruḥ \
yad u śuklam ivābhūd ity apāṃ rūpam iti tad vidāṃ cakruḥ \
yad u kṛṣṇam ivābhūd ity annasya rūpam iti tad vidāṃ cakruḥ \\604.6\

6. They knew that whatever appeared red was the form of

heat. They knew that whatever appeared white was the form of water. They knew that whatever appeared dark was the form of food.

6.4.7

yad v avijñātam ivābhūd ity etāsām eva devatānāṃ samāsa iti tad vidāṃ cakruḥ \
yathā nu khalu (S ) tisro devatāḥ puruṣaṃ prāpya trivṛt trivṛd ekaikā bhavati tan me vijānīhīti \\604.7\

7. They knew that whatever appeared un-understood, is a combination of just these divinities.

Verily, my dear, understand from me how each of these three divinities, upon reaching man, becomes threefold.
