In plain words
The poet, to the Lord: O you who bear the discus, who brought to nothing the boons that [Hiraṇya and others] won from the four-faced one [Brahmā] by their penance: is it not you who gladly protect us? Is not the resolve to protect yours alone? And is it not you who give Vaikuṇṭha to every soul [that comes to you]?
