Chandogya Upanishad Excerpt

In the center of the castle of Brahman, our own body,
There is a small shrine in the form of a lotus flower
and within can be found a small space.

We should find who dwells there and we should want to know him.
And if anyone asks,  "Who is he who lives in a small shrine
in the form of a lotus flower in the center of the castle of Brahman?"

We can answer:
"The little space within the heart is as great as the universe.
The heaven and the earth are there; the sun, the moon, the stars;
fire and lightening and winds ...
For the whole universe is in Him and He dwells within our hearts."
