Mahabharata Shalya Parva Chapter 35:3

Mahabharata Shalya Parva (Gada Yuddha Parva) Chapter 35:3 Vaishampayana said, "Daksha had seven and twenty daughters, O king! These he bestowed (in marriage) upon Soma. Connected with the several constellations, those wives, O king, of Soma of auspicious deeds, served to help men in calculating time. Possessed of large eyes, all of them were unrivalled in beauty in the world. In wealth of beauty, however, Rohini was the foremost of them all. The adorable Soma took great delight in her. She became very agreeable to him, and therefore, he enjoyed the pleasures of her company (exclusively). In those days of yore, O monarch, Soma lived long with Rohini (exclusively). For this, those other wives of his, they that were called the constellations, became displeased with that high-souled one. Repairing speedily to their sire (Daksha), that Lord of creation, they said unto him, 'Soma doth not live with us! He always payeth court to Rohini only! All of us, therefore, O Lord of creatures, shall dwell by thy side, on regulated diet and observant of austere penances!' Hearing these words of theirs, Daksha (saw Soma and) said unto him, 'Behave equally towards all thy wives! Let not a great sin stain thee!' And Daksha then said unto those daughters of his, 'Go, all of you, to the presence of Sasin. At my command, he, (otherwise called) Candramas, will behave equally towards all of you!' Dismissed by him, they then proceeded to the abode of him having cool rays. Still the adorable Soma, O lord of earth, continued to act as before, for pleased with Rohini alone, he continued to live with her exclusively. His other wives then once more came together to their sire and said unto him, 'Employed in serving thee, we will dwell in thy asylum! Soma does not live with us and is unmindful of thy commands!' Hearing these words of theirs, Daksha once more said unto Soma, 'Behave equally towards all thy wives! Let me not, O Virochana, curse thee!' Disregarding, however, these words of Daksha, the adorable Soma continued to live with Rohini alone. At this, his other wives became once more angry. Repairing to their sire, they bowed unto him by lowering their heads, and said, 'Soma doth not live with us! Give us thy protection! The adorable Candramas always lives with Rohini exclusively! He sets no importance to thy words, and does not wish to show us any affection! Therefore, save us so that Soma may accept us all!' Hearing these words, the adorable Daksha, O king, became angry and in consequence thereof hurled the curse of phthisis upon Soma. Thus did that disease overtake the Lord of the stars. Afflicted with phthisis, Sasin began to waste away day by day. He made many endeavours for freeing himself from that disease by performing diverse sacrifices, O monarch! The maker of night, however, could not free himself from that curse. On the other hand, he continued to endure waste and emaciation. In consequence, however, of the wasting of Soma, the deciduous herbs failed to grow. Their juices dried up and they became tasteless, and all of them became deprived of their virtues. And, in consequence of this decadence of the deciduous herbs, living creatures also began to decay.
