In Hindu mythology, one of four sages
born of the god Brahma, who are
paradigms of asceticism; the other
three are Sanandana, Sanatana,
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.
