In plain words
The poet, to the people of the world: He set up lesser gods everywhere [for those of passion and dullness to worship], and by his own matchless good grace he pointed out Tiruvaraṅgam, so that those who would be saved might be saved. Did you hear, fine sirs? While he whose mount is Garuḍa stands here, you sit waiting for wealth in the lap of Misfortune [the goddess of penury].
