parāśara uvāca:
evaṃ dadau varau devī devarājāya vai purā
maitreya śrīr mahābhāgā stotrārādhanatoṣitā //

Paráśara proceeded.--Thus, Maitreya, in former times the goddess Śrí conferred these boons upon the king of the gods, being pleased by his adorations; but her first birth was as the daughter of Bhrigu by Khyáti: it was at a subsequent period that she was produced from the sea, at the churning of the ocean by the demons and the gods, to obtain ambrosia. For in like manner as the lord of the world, the god of gods, Janárddana, descends amongst mankind (in various shapes), so does his coadjutrix Śrí. Thus when Hari was born as a dwarf, the son of Adití, Lakshmí appeared from a lotus (as Padmá, or Kamalá); when he was born as Ráma, of the race of Bhrigu (or Paraśuráma), she was Dharańí; when he was Rághava (Rámachandra), she was Sítá; and when he was Krishńa, she became Rukminí. In the other descents of Vishńu, she is his associate. If he takes a celestial form, she appears as divine; if a mortal, she becomes a mortal too, transforming her own person agreeably to whatever character it pleases Vishńu to put on. Whosoever hears this account of the birth of Lakshmí, whosoever reads it, shall never lose the goddess Fortune from his dwelling for three generations; and misfortune, the fountain of strife, shall never enter into those houses in which the hymns to Śrí are repeated.
