Nastika

(“nihilists”) In Hindu philosophical discourse, this was a pejorative term to
denigrate certain other religious and
philosophical schools. The name
Nastika was applied to groups who
denied the three most basic principles
of religion: the authority of the Vedas as
religious texts, the eternal existence of
the soul (atman), and the value of religious life in general. In context this term
could be applied to the Jains (who
denied the first of these three) to the
Buddhists (who denied the first and the
second) or to the materialist philosophical school (which denied all three).
