Brahman refers to the ultimate reality and supreme cosmic power that pervades everything in existence. According to the Upanishads, particularly the Chandogya Upanishad, Brahman is both the material and efficient cause of the universe.
The concept is explained through the Sanskrit maxim 'Tat Tvam Asi' (That Thou Art), indicating that individual consciousness (Atman) is identical with universal consciousness (Brahman). Modern physics' understanding of the unified field bears striking parallels to this ancient concept of an all-pervading cosmic reality.
This philosophical framework provides the foundation for Hindu practices like meditation and self-inquiry, aimed at realizing this ultimate truth through direct experience rather than mere intellectual understanding.
