KAUSITAKI UPANISHAD

“Who art thou?” The sage asks. “I am thou,” he replies.

Being freed from good and freed from evil he, the knower of Brahman, moves towards Brahman. Only by knowledge he sees clearly.

I am like a season, and the child of the seasons, sprung from the womb of the endless space, from the light from the luminous Brahman. The light, the origin of the year, which is the past, which is the present, which is all living beings, and all elements, is the Atman. Thou art the Atman. What thou art, that am I.

When a person is so asleep that he sees no dream whatever, then he becomes one with that vital breath. Then speech together with all names goes to it; the eye together with all forms goes to it; the ear together with all sounds goes to it; the mind together with all thoughts goes to it. When he awakes, as from a blazing fire sparks would fly in all directions, even so from this self the vital breaths proceed to their respective stations; from the vital breaths, the senses, from the gods, the worlds. The same vital breath, the self of intelligence, seizes hold of the body and raises it up. 

One has to win the pure knowledge of the unity of Brahman and Atman

Speech is not what one should seek to know, one should know the speaker

Smell is not what one should seek to know, one should know the smeller.

Form is not what one should seek to know, one should know the seer.

Sound is not what one should seek to know, one should know the hearer.

Taste of food is what one should seek to know, one should know the knower of the taste of food.

Deed is not what one should seek to know, one should know the doer.

Pleasure and pain are not what one should seek to know; one should know the discerner of pleasure and pain.

Bliss, delight and procreation are not what one should seek to know, one should know the discerner of bliss, delight and procreation.

Going is not what one should seek to know, one should know the goer.

Mind is not what one should seek to know, one should know the thinker.
