In plain words
Yaśōdā calls: "You who became the messenger of the five [Pāṇḍavas] and then gave your help in the Bhārata war; who went into the dread pool where the poison-spitting serpent [Kāḷiya] lay, leapt onto its hoods till it cowered, and then showed it grace: you coloured like kohl, accō, accō! Lord of the herdsmen, accō, accō!"
