Bahiryaga

(“external sacrifice”) In Hindu worship,
especially in esoteric ritual tradition
known as tantra, bahiryaga refers to any
type of religious practice involving
actions, words, or the manipulation of
concrete objects. This is the only kind of
worship that most people perform. The
ultimate goal in tantra, however, is to
internalize these acts through repeated
practice and to transform them into
antaryaga (“internal sacrifice”), in
which all external actions have been
replaced by mental acts.
