From the vijnanam to the annam is the aparardha or lower part of existence where Vidya is dominated by Avidya; from the ananda to the sat is the parardha or higher half in which Avidya is dominated by Vidya and there is no ignorance, pain or limitation.

Man, according to Vedic psychology, consists of seven principles, in which the Atman cases itself,—annam, gross matter; prana, vital energy; manas, intelligent mind; vijnanam, ideal mind; ananda, pure or essential bliss; chit, pure or essential awareness; sat, pure or essential being.
