There is this city of Brahman (the human body) and in it there is a small shrine in the form of a lotus, and within can be found a small space. This little space within the heart is as great as this vast universe. The heavens and the earth are there, and the sun and the moon and the stars; fire and lightening and wind are there, and all that now is and is not yet - all that is contained within it.

• Chandogya Upanishad
