Even if devotees excuse those who insult them, Krishna takes a diffrent position and he is strict on this matter. Krishna will not excuse or tolerate any insult of his devotees. If we want to please Krishna, we must never insult his devotees. — Lecture on Bhagavad Gita, 01.26-27, London, 1973.
A pure devotee has no demand from the Lord. His only concern is to serve the Lord sincerely and seriously and he is not at all concerned about what will happen in the future. — Srimad Bhagavatam, 04.09.29.
Devotees are not impressed by the poverty or wealth in material sense in any way; what impresses is devotion.
A devotee is surrendered to whatever Krishna wants. If Krishna wants him to take birth again, he will take, but he prays to remain in the association of devotees.
