Kauṣītaki Upaniṣad 2.1

2.1

Prâna (breath) is Brahman, thus says Kaushîtaki. Of this prâna, which is Brahman, the mind (manas) is the messenger, speech the housekeeper, the eye the guard, the ear the informant. He who knows mind as the messenger of prâna, which is Brahman, becomes possessed of the messenger. He who knows speech as the housekeeper, becomes possessed of the housekeeper. He who knows the eye as the guard, becomes possessed of the guard. He who knows the ear as the informant, becomes possessed of the informant.
Now to that prâna, which is Brahman, all these deities (mind, speech, eye, ear) bring an offering, though he asks not for it, and thus to him who knows this all creatures bring an offering, though he asks not for it. For him who knows this, there is this Upanishad (secret vow), 'Beg not!' As a man who has begged through a village and got nothing sits down and says, 'I shall never eat anything given by those people,' and as then those who formerly refused him press him (to accept their alms), thus is the rule for him who begs not, but the charitable will press him and say, 'Let us give to thee.'
