Aitareya Upanishad

1. ‘Who is he?’

‘We worship him as the self.’

‘Which one is the self?’

‘The one by whom one sees, by whom one hears, by
whom one smells smells, by whom one utters speech, by
whom one discriminates what is sweet and not sweet?

2. ‘Who is the heart, the mind; consciousness, perception,
discrimination, knowledge, intelligence, vision,
steadfastness, thought, consideration, swiftness,
memory, resolve, intention, life, desire, will. All these
are names for knowledge.

3. He is Brahma, he is Indra, he is Prajapati and all the
gods; the five elements earth, air, space, the waters, light;
those which are, as it were, finely mixed; the various other
kinds of seeds, the egg-born, the womb-born, the
sweat-born, the shoot-born; horses, cattle, human beings, elephants. All that has breath, both walking and
flying, and all that is still, is led by knowledge, based on
knowledge. The world is led by knowledge. Knowledge is
the basis. Knowledge is brahman.

4. By the wise self he rose upwards; he won in that
heavenly world all desires; and he became immortal, became
immortal. So it is. OM.

OM. My speech stands firm on mind:

My mind stands firm on speech.

Appear, appear to me.

Be to me a nail for the Veda.

Do not harm that which I have heard.

With this study I hold days and nights together.

I will speak law: I will speak truth.
May that protect me: may that protect the speaker.
May it protect me: may it protect the speaker,
may it protect the speaker.

OM, Peace, peace, peace.
