Mbh 12.343.3b

The rest of his spouses, filled with jealousy, leaving him, repaired to their sire and informed him of this conduct of their husband, saying,--'O holy one, although all of us are equal in point of beauty, yet our husband Shoma is exclusively attached to our sister Rohini.'--Incensed at this representation of his daughters, the celestial Rishi Daksha cursed Shoma, saying, that thenceforth the disease phthisis should assail his son-in-law and dwell in him. Through this curse of Daksha, phthisis assailed the puissant Shoma and entered into his body. Assailed by phthisis in this way, Shoma came to Daksha. The latter addressed him, saying,--'I have cursed thee because of thy unequal behaviour towards thy wives.' The Rishi then said unto Shoma,--'Thou art being reduced by the disease phthisis that has assailed thee. There is a sacred water called Hiranyasarah in the Western ocean. Repairing to that sacred water, do thou bathe there.'--Counselled by the Rishi, Shoma proceeded thither. Arrived at Hiranyasarah, Soma bathed in that sacred water. Performing his oblations he cleansed himself from his sin. And because that sacred water was illumined (abhasita) by Shoma, therefore was it from that day called by the name of Prabhasa. In consequence, however, of the curse denounced upon him in days of old by Daksha, Shoma, to this day, begins to wane from the night of the full moon till his total disappearance on the night of the new moon whence he once more begins to wax till the night of full moon. The brightness also of the lunar disc from that time received a stain, for the body of Shoma, since then, has come to present certain dark spots. In fact, the splendid disc of the moon has, from that day, come to exhibit the mark of a hare. Once on a time, a Rishi of the name of Sthulasiras was engaged in practising very severe austerities on the northern breasts of the mountains of Meru.
