Brahman - The Absolute Reality
The ultimate, unchanging reality underlying all existence.
Brahman is the infinite, eternal, unchanging ground of all being. It is beyond all descriptions yet is the essence of everything. The Upanishads declare that knowing Brahman is the highest knowledge.
Brahman is real, the world is appearance, the individual soul is Brahman alone.
Understanding Brahman liberates from the cycle of birth and death.
