This Puráńa, originally composed by the Rishi (Náráyańa), was communicated by Brahmá to Ribhu; he related it to Priyavrata, by whom it was imparted to Bháguri. Bháguri recited it to Tamasitra, and he to Dadícha, who gave it to Sáraswata. From the last Bhrigu received it, who imparted it to Purukutsa, and he taught it to Narmadá. The goddess delivered it to Dhritarásht́ra the Nága king, and to Puráńa of the same race, by whom it was repeated to their monarch Vásuki. Vásuki communicated it to Vatsa, and he to Áswatara, from whom it successively proceeded to Kambala and Elapatra. When the Muni Vedaśiras descended to Pátála, he there received the whole Puráńa from these Nágas, and communicated it to Pramati. Pramati consigned it to the wise Játukarńa, and he taught it to many other holy persons. Through the blessing of Vaśisht́ha it came to my knowledge, and I have now, Maitreya, faithfully imparted it to you. You will teach it, at the end of the Kali age, to Śamíka. Whoever hears this great mystery, which removes the contamination of the Kali, shall be freed from all his sins. He who hears this every day acquits himself of his daily obligations to ancestors, gods, and men. The great and rarely attainable merit that a man acquires by the gift of a brown cow, he derives from hearing ten chapters of this Puráńa. He who hears the entire Puráńa, contemplating in his mind Achyuta, who is all things, and of whom all things are made; who is the stay of the whole world, the receptacle of spirit; who is knowledge, and that which is to be known; who is without beginning or end, and the benefactor of the gods--obtains assuredly the reward that attends the uninterrupted celebration of the Aśwamedha rite. He who reads and retains with faith this Puráńa, in the beginning, middle, and end of which is described the glorious Achyuta, the lord of the universe in every stage, the master of all that is stationary or moveable, composed of spiritual knowledge, acquires such purity as exists not in any world, the eternal state of perfection, which is Hari. The man who fixes his mind on Vishńu goes not to hell: he who meditates upon him regards heavenly enjoyment only as an impediment: and he whose mind and soul are penetrated by him thinks little of the world of Brahmá; for when present in the minds of those whose intellects are free from soil, he confers upon them eternal freedom. What marvel therefore is it that the sins of one who repeats the name of Achyuta should be wiped away? Should not that Hari be heard of, whom those devoted to acts worship with sacrifices continually as the god of sacrifice; whom those devoted to meditation contemplate as primary and secondary, composed of spirit; by obtaining whom man is not born, nor nourished, nor subjected to death; who is all that is, and that is not (or both cause and of effect); who, as the progenitors, receives the libations made to them; who, as the gods, accepts the offerings addressed to them; the glorious being who is without beginning or end; whose name is both Swáhá and Swadhá; who is the abode of all spiritual power; in whom the limits of finite things cannot be measured; and who, when he enters the ear, destroys all sin?
