'Celestial Dynasties' refers to those of the sun and moon gods, in which both Lord Rama and Lord Krishna respectively appeared. The ninth canto traces both lines up to their appearances, giving details of their significant ancestors such as King Ambarisha, who overcame the powerful mystic Durvasa; Parasurama, who destroyed the world's kshatriyas twenty-one times; Pururava, who married the celestial girl, Urvasi; King Yayati, who wed Sage Shukra's daughter, Devayani, only to be cursed by him with premature old age; plus many other fascinating accounts of sages, kings and gods who preceded the two divine incarnations. The authors give a dramatic rendition of the original text, which both entertains and educates, bringing out the profound messages of the Bhagavatam.
