Upanishad, Upanisad
Upanishad, Upanisad
(Skr.) One of a large number of treatises, more than 100. Thirteen of the oldest ones (Chandogya, Brhadaranyaka, Aitareya, Taittiriya, Katha, Isa, Mundaka, Kausitaki, Kena, Prasna, Svetasvatara, Mandukya, Maitri) have the distinction of being the first philosophic compositions, antedating for the most part the beginnings of Greek philosophy, others have been composed comparatively recently. The mode of imparting knowledge with the pupil sitting opposite (upa-ni-sad) the teacher amid an atmosphere of reverence and secrecy, gave these onginally mnemonic treatises their name. They are remarkable for ontological, metaphysical, and ethical problems, investigations into the nature of man’s soul or self (see atman), God, death, immortality, and a symbolic interpretation of ritualistic materials and observances. Early examples of universal suffrage, tendencies to break down caste, philosophic dialogues and congresses, celebrated similes, succession of philosophic teachers, among other things, may be studied in the more archaic, classical Upanishads.
