This vast universe is a wheel, the wheel of Brahman. Upon it are all creatures that are subject to birth, death, and rebirth. Round and round it turns, and never stops. As long as the individual self thinks it is separate from the Lord, it revolves upon the wheel in bondage to the laws of birth, death, and rebirth.... The Lord supports this universe, which is made up of the perishable and the imperishable, the manifest and the unmanifest. The individual soul, forgetful of the Lord, attaches itself to pleasure and thus is bound.

(The Upanishads)
