In plain words
The poet, to the Lord: O you who were Death to Kālanemi! O you of fame beyond counting! O you whose nature it was, long ago [at the close of an age], to become a matchless infant and swallow the seven worlds! O hero of conquering wrath, who bent your bow so that the waters of the sea boiled! O great one, who frees the hearts of the devotees who belong to you from every other attachment!
