1.14.9

parāśara uvāca:
pitrā pracetasaḥ proktāḥ prajārtham amitātmanā
prajāpatiniyuktena bahumānapuraḥsaram //

PARÁŚARA.--The sons of Práchínaverhis were originally informed by their father, who had been appointed as a patriarch, and whose mind was intent on multiplying mankind, that the had been respectfully enjoined by Brahmá, the god of gods, to labour to this end, and that he had promised obedience: "now therefore," continued he, "do you, my sons, to oblige me, diligently promote the increase of the people, for the orders of the father of all creatures are entitled to respect." The sons of the king, having heard their father's words, replied, "So be it;" but they then inquired of him, as he could best explain it, by what means they might accomplish the augmentation of mankind. He said to them; "Whoever worships Vishńu, the bestower of good, attains undoubtedly the object of his desires: there is no other mode. What further can I tell you? Adore therefore Govinda, who is Hari, the lord of all beings, in order to effect the increase of the human race, if you wish to succeed. The eternal Purushottama is to be propitiated by him who wishes for virtue, wealth, enjoyment, or liberation. Adore him, the imperishable, by whom, when propitiated, the world was first created, and mankind will assuredly be multiplied."
