Vedanta-sutra is the ultimate knowledge of the Vedas. Vedic knowledge is very elevated, having issued forth from Maha-Viṣṇu, the Supreme Godhead, at the time of creation. The Vedanta-sutras are extremely recondite and esoteric, and are thus accessible to ordinary human intelligence only in the context of a commentary. The first Adhikarana or topic of Vedanta begins the inquiry into the Absolute or Brahman. Everyone should inquire very seriously about the Absolute, because knowledge of the Absolute—the science of consciousness—is the only source of unconditional happiness. There is no other means to obtain perfect, uninterrupted, endless happiness, because consciousness is the fundamental existential issue. Such exalted happiness is possible only through understanding and practicing the recondite truths of Vedanta in regard to one’s personal relationship with the Absolute.
