The Sanskrit texts make it clear that a cataclysm on this scale, though a relatively rare event, is expected to wash away all traces of the former world and that the slate will be wiped clean again for the new age of the earth to begin. In order to ensure that the Vedas can be repromulgated for future mankind after each pralaya the gods have therefore designed an institution to preserve them -- the institution of the Seven Sages, a brotherhood of adepts possessed of unerring memories and supernatural powers, practitioners of yoga, performers of the ancient rituals and sacrifices, ascetics, spiritual visionaries, vigilant in the battle against evil, great teachers, knowledgeable beyond all imagining, who reincarnate from age to age as the guides of civilization and the guardians of cosmic justice.
