Vaisnava never takes revenge anyone

Q: Nalakuvara and Manigriva mis-behaved with great devotee Narada Muni. They were puffed up and intoxicated. They were cursed and became trees.
How is that they got chance to see Krishna's past times so close and became great devotees?  Why were they destined to take birth in Vrndavan - they should have gone to lowest of region for their mis-behaviour (against pure devotee) right?

A: A vaisnava​ never wants to take revenge over any one who ridicules him. There is no difference between blessing and cursing of a Vaisnava.Both are for one's advancement in KC.
Narada Muni cursed them to become naked in their next life immediately. Because of their apology Narada Muni forgave them and informed that they would be trees in Nanda Maharaja 's court yard and be delivered by Krsna.
In fact a Vaisnava never takes revenge instead try to help to advance spiritually.
Hari Bol.
