Sanatana

In Hindu mythology, one of four sages
born of the god Brahma who are paradigms of asceticism; the other three
ascetics are Sanaka, Sanandana, and
Sanatkumara. When Brahma emanates
these four sages, he commands them
to begin the work of creation, but they
are so detached from worldly concerns that they refuse to do so. They
are celibate their entire lives, study
the Vedas from childhood, and always
travel together.
