Mbh 12.349.2e

Daksha, in his turn, imparted it to the eldest of all the sons of his daughters, O monarch, viz., Aditya who is senior in age to Savitri. From Aditya, Vivaswat obtained it. In the beginning of the Treta Yuga, Vivaswat imparted the knowledge of this cult to Manu. Manu, for the protection and support of all the worlds, then gave it to his son Ikshaku.[1904] Promulgated by Ikshaku, that cult over-spreads the whole world. When the universal destruction comes, it will once more return to Narayana and be merged in Him. The religion which is followed and practised by the Yatis, has, O best of kings, been narrated to thee before this in the Hari Gita, with all its ordinances in brief. The celestial Rishi Narada got it from that Lord of universe, viz., Narayana himself, O king, with all its mysteries and abstract of details. Thus, O monarch, this foremost of cults is primeval and eternal. Incapable of being comprehended with ease and exceedingly difficult of being practised, it is always upheld by persons wedded to the attribute of Sattwa. It is by means of acts that are well-performed and accomplished with a full knowledge of duties and in which there is nothing of injury to any creature,--that Hari the Supreme Lord becomes gratified. Some persons adore Narayana as possessed of only one form, viz., that of Aniruddha. Some adore Him as endued with two forms, viz., that of Aniruddha and Pradyumna. Some adore Him as having three forms, viz., Aniruddha, Pradyumna, and Sankarshana. A fourth class adore him as consisting of four forms, viz., Aniruddha, Pradyumna, Sankarshana, and Vasudeva. Hari is Himself the Kshetrajna (Soul). He is without parts (being ever full). He is the Jiva in all creatures, transcending the five primal elements. He is the Mind, O monarch, that directs and controls the five senses. Endued with the highest intelligence, He is the Ordainer of the universe, and the Creator thereof. He is both active and inactive. He is both Cause and the Effect.
