There is rescue from every trouble and calamity in the daily recitation of the names of the deities of the seven Rishis, and of Dhruva. Indeed, such recitation speedily frees one from distress. The sages of olden times, viz., Kasyapa, Gotama, and others, and Bhrigu Angiras and Atri and others, and Sukra, Agastya, and Vrihaspati, and others, all of whom are regenerate Rishis, have adored these Mantras. Approved of by the son of Bharadwaja, these Mantras were attained by the sons of Richika. Verily, having acquired them again from Vasishtha, Sakra and the Vasus went forth to battle and succeeded in subjugating the Danavas. That man who makes a present of a hundred kine with their horns covered with plates of gold unto a Brahmana possessed of much learning and well-conversant with the Vedas, and he who causes the excellent Bharata story to be recited in his house every day, are said to acquire equal merits. By reciting the name of Bhrigu one's righteousness becomes enhanced. By bowing to Vasishtha one's energy become enhanced. By bowing unto Raghu, one becomes victorious in battle. By reciting the praises of the Aswins, one becomes freed from diseases. I have thus, O king, told thee of the Savitri Mantras which are identical with eternal Brahman. If thou wishest to question me on any other topic thou mayst do so. I shall, O Bharata, answer thee."'"
