Once Saunaka of the line of Kapi and Abhipratarin, the son of Kakshasena, were being waited upon at their meal, when a brahmacharin begged food of them. They did not give him anything.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 5
He said: One God, Prajapati, swallowed the four great ones. He is the Guardian of the world. O descendent of Kapi, O Abhipratarin, mortals do not see Him though he abides in manifold forms. Verily, this food has not been given to Him to whom it belongs.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 6
Sanaka of the line of Kapi, pondering on those words, went to the brahmacharin and said: He is the self of the gods, the creator of all beings, with unbroken teeth, the eater, the truly wise one. They speak of His magnificence as great, because withoutbeing eaten, He eats even what is not common food. O brahmacharin, we meditate upon this Brahman. Then he said to the attendants: Give him food.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 7
They gave food to him. Now these five (i.e. the eater vayu and fire, the sun, the moon and water, which are its food) and those five (i.e. the eater prana and the organs of speech, the eye, the ear and the mind, which are its food) make ten. These together constitute the krita (the highest throw in a game of dice). On account of this similarity of ten, these ten are the food in the ten quarters and further, they are Virat, the eater of food, by which all this becomes seen. All this he sees and the eater of food he becomes, who knows this, yea, who knows this.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 8
Once upon a time, Satyakama the son of Jabala addressed his mother and said: Revered Mother, I wish to become a brahmacharin. Of what ancestry am I?
Sama Veda, Chandogya Upanishad IV, IV – The Story of Satyakama, 1
