Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
I, knowing, hurl at this man, to split his head, the four-pointed (-bhṛṣṭí) thunderbolt of the waters; let it crush all his limbs: to this on my part let all the gods assent.
Translated by William Dwight Whitney (1905)
