Isshvasya Upanishad

Isshvasya Upanishad:

Purnamadah, purnamidam l

Purnat purnamudacyate l

Purnasya purnamadaya l

Purnameva avasisyate.

That is complete, this is complete;

From that completeness comes this completeness.

When completeness is taken away from completeness,

Completeness alone remains.

This is the law of conservation of energy as it is now known to scientists. It states that energy or its equivalent in mass can neither be created nor destroyed. The sum total of mass and energy remains constant. Nothing extra can be added to it nor can anything be subtracted from it. That completeness is Brahman--the ever complete Reality that exists even in the vacuum. Brahman manifests in various forms and cannot be subjected to addition or subtraction.
