Excerpts from the Chandogya Upanishad

Wherefrom do all these worlds come? They come from space. All beings arise from space, and into space they return: space is indeed their beginning, and space is their final end.

1.9.1

Prajapati, the Creator of all, rested in life-giving meditation over the worlds of his creation; and from them came the three Vedas. He rested in meditation and from those came the three sounds: BHUR, BHUVAS, SVAR, earth, air, and sky. He rested in meditation and from the three sounds came the sound OM. Even as all leaves come from a stem, all words come from the sound OM. OM is the whole universe, OM is in truth the whole universe.

2. 23. 2

Great is the Gayatri, the most sacred verse of the Vedas; but how much greater is the Infinity of Brahman! A quarter of his being is this whole vast universe: the other three quarters are his heaven of Immortality.

3. 12. 5

There is a Light that shines beyond all things on earth, beyond us all, beyond the heavens, beyond the highest, the very highest heavens. This is the Light that shines in our heart.

3. 13. 7

All this universe is in truth Brahman.

He is the beginning and end and life of all. As such, in silence, give unto him adoration.

Man in truth is made of faith.

As his faith is in this life, so he becomes in the beyond: with faith and vision let him work.

There is a Spirit that is mind and life, light and truth and vast spaces. He contains all works and desires and all perfumes and all tastes. He enfolds the whole universe, and in silence is loving to all.

This is the Spirit that is in my heart, smaller than a grain of rice, or a grain of barley, or a grain of mustard-seed, or a grain of canary-seed, or the kernel of a grain of canary-seed. This is the Spirit that is in my heart, greater than the earth, greater than the sky, greater than heaven itself, greater than all these worlds.

He contains all works and desires and all perfumes and all tastes. He enfolds the whole universe and in silence is loving to all.

This is the Spirit that is in my heart, this is Brahman.

To him I shall come when I go beyond this life. And to him will come he who has faith and doubts not.

Thus said Sandilya, thus said Sandilya.
