Shloka 1.70.37
वंशवर्णनम् तथा विवाहप्रार्थना — Genealogy of the Ikshvaku Line and the Proposal for Marriage
सपत्न्या तु गरस्तस्यै दत्तो गर्भजिघांसया।सह तेन गरेणैव जात: स सगरोऽभवत्।।1.70.37।।
sapatnyā tu garas tasyai datto garbhajighāṃsayā | saha tena gareṇaiva jātaḥ sa sagaro 'bhavat || 1.70.37 ||
But her rival queen gave her poison, intending to destroy the embryo; and the child was born with that very poison—thus he became known as Sagara.
Since poison was given to her by her rival queen with the intention of destroying the embryo, the son was born with poison and so came to be known as Sagara.
The verse contrasts dharma with adharma: jealousy-driven harm toward an unborn child is condemned implicitly, while truth prevails as the child survives and is acknowledged by name and story.
A rival queen attempts fetal harm by administering poison; nevertheless, the child is born, acquiring the name Sagara due to that circumstance.
Endurance and the triumph of rightful destiny over malicious intent; the rival’s vice (envy) is the cautionary focus.
