In plain words
The poet, to the Lord: O you who for Piṉṉai's sake stood [unafraid] before the strong, rampaging bulls [the seven] and, thinking out the way, destroyed their might; O you who hold the great conch whorled within: was it not you who destroyed Hiraṇya, who could not live at one with you, and you who went, asked and received the great earth?
