I WILL first relate to you the family of Yadu, the eldest son of Yayáti, in which the eternal immutable Vishńu descended upon earth in a portion of his essence; of which the glory cannot be described, though for ever hymned in order to confer the fruit of all their wishes--whether they desired virtue, wealth, pleasure, or liberation--upon all created beings, upon men, saints, heavenly quiristers, spirits of evil, nymphs, centaurs, serpents, birds, demons, gods, sages, Brahmans, and ascetics. Whoever hears the account of the race of Yadu shall be released from all sin; for the supreme spirit, that is without form, and which is called Vishńu, was manifested in this family.
