yuge yuge bhavanty ete dakṣādyā munisattama
punaś caiva niruddhyante vidvāṃs tatra na muhyati //

PARÁŚARA.--Birth and death are constant in all creatures: Rishis and sages, possessing divine vision, are not perplexed by this. Daksha and the other eminent Munis are present in every age, and in the interval of destruction cease to be: of this the wise man entertains no doubt. Amongst them of old there was neither senior nor junior; rigorous penance and acquired power were the sole causes of any difference of degree amongst these more than human beings.
