Vishnupurana 2.12.p4

2.12.p4

I have related to you, O foremost of Munis, that Dhruva is fitted to the tail of the celestial porpoise: I shall now describe in detail the constituent parts; hear them as they are of great efficacy. People are freed from the sins committed by them during the day when they behold the celestial porpoise in the hight. And those who behold it live as many years as there are stars in it, in the sky or even more. Uttānpada is the upper jaw and sacrifice the lower jaw of that celestial porpoise. Dhruva is situated on its brow and Nārāyana in its heart. The Aswinis are its two fore-feet and Varuna and Aryamat are its two hinder legs. Samvatsara is its sexual organ and Mitra is its organ of execretion. Agni, Mahendra, Kasyapa and Dhurva are successively placed in its tail; which four stars in this constellation never set.
