iksvakunam ayam vamsah
yatas tam prapya rajanam
samstham prapsyati vai kalau
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The last king in the dynasty of Iksvaku will be Sumitra; after Sumitra there will be no more sons in the dynasty of the sun-god, and thus the dynasty will end.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thus end the Bhaktivedanta purports of the Ninth Canto, Twelfth Chapter, of the Srimad-Bhagavatam, entitled “The Dynasty of Kusa, the Son of Lord Ramacandra.”
