In plain words
The poet, surrendering to the Lord of Viṟṟuvakkōṭu: Even if red fire itself comes close and gives it heat, the red lotus opens for nothing but the sun whose hot rays stand in the sky. So, O Lord of Viṟṟuvakkōṭu, even if you do not destroy my cruel sins, my heart will melt for nothing but your boundless auspicious qualities.
