vyāsa uvāca |
iti pṛṣṭastathā tena brāhmaṇaḥ saṃśitavrataḥ |
uvāca paramaprītastaṃ vaiśyaṃ nṛpasattama ||

Vyâsa said:-- The Brâhmin that used to practice vows when thus asked by the trader told him gladly “O trader! Do now the Navarâtri vow, the most auspicious, and worship the Bhagavatî, perform Homa, and feast the Brâhmins. Have the Vedas and Purânas recited and recite then slowly the S’akti mantram and try, as much as you can, to do other concomitant ceremonies; and your desires will thus be undoubtedly fulfilled.
