CHĀNDOGYA UPANISHAD · 4.3.8

तस्मै उ ह ददुः ।
ते वा एते पञ्चान्ये पञ्चान्ये दश सन्तस् तत् कृतम् ।
तस्मात् सर्वासु दिक्ष्व् अन्नम् एव दश कृतम् ।
सैषा विराड् अन्नादी ।
तयेदं सर्वं दृष्टम् ।
सर्वम् अस्य इदं दृष्टं भवत्य् अन्नादो भवति य एवं वेद य एवं वेद ॥

tasmai u ha daduḥ ।
te vā ete pañcānye pañcānye daśa santas tat kṛtam ।
tasmāt sarvāsu dikṣv annam eva daśa kṛtam ।
saiṣā virāḍ annādī ।
tayedaṃ sarvaṃ dṛṣṭam ।
sarvam asya idaṃ dṛṣṭaṃ bhavaty annādo bhavati ya evaṃ veda ya evaṃ veda ॥

They gave him food. Now these five (the eater Vâyu (air), and his food, Agni (fire), Âditya (sun), Kandramas (moon), Ap (water)) and the other five (the eater Prâna (breath), and his food, speech, sight, hearing, mind) make ten, and that is the Krita (the highest ) cast (representing the ten, the eaters and the food). Therefore in all quarters those ten are food (and) Krita (the highest cast). These are again the Virâg (of ten syllables) which eats the food. Through this all this becomes seen. He who knows this sees all this and becomes an eater of food, yea, he becomes an eater of food.
