Then considering her (the princess) as the door for imparting knowledge, Raikva said: O Sudra! You brought these cows and other presents; this is good. But you will make me speak now only through this means (i.e. the princess). These are the villagesnamed Raikvaparna, in the country of Mahavrishas, where Raikva lived. Now Raikva said to the king:
Sama Veda, Chandogya Upanishad IV, II – Dialogue of Raikva and Janasruti (I), 5
Verily, Vayu (the air) is the swallower (samvarga). For when fire goes out it is indeed swallowed by the air. When the sun sets it is swallowed by the air. When the moon sets it is swallowed by the air.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 1
When water dries up it is swallowed by the air. For indeed the air absorbs them all. So much with reference to the gods.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 2
Now with reference to the body: Verily, the prana is the swallower. When a man sleeps, speech goes into the prana, sight goes into the prana, hearing goes into the prana and the mind goes into the prana. For indeed the prana absorbs them all.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 3
These are the two swallowers: the air among the gods, the prana among the senses.
Sama Veda, Chandogya Upanishad IV, III – Dialogue of Raikva and Janasruti (II), 4
