garo datto ’ndhasa saha
saha tenaiva sañjatah
sagaras cakravarty asit
sagaro yat-sutaih krtah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Knowing that she was pregnant, the co-wives of the wife of Bahuka conspired to give her poison with her food, but it did not act. Instead, the son was born along with the poison. Therefore he became famous as Sagara [“one who is born with poison”]. Sagara later became the emperor. The place known as Gangasagara was excavated by his sons.
