Brahman In Hinduism, Brahman (/ˈbrɑːhmən/) connotes the highest Universal Principle, the Ultimate Reality in the universe.[1][2][3] In major schools of Hindu philosophy, it is the material, efficient, formal and final cause of all that exists.[2][4][5] It is the pervasive, genderless, infinite, eternal truth and bliss which does not change, yet is the cause of all changes.[1][6][7] Brahman as a metaphysical concept is the single binding unity behind diversity in all that exists in the universe.[1][8]
