From this statement by Haridasa Thakura, it is understood that a pure Vaisnava never takes anyone's insults seriously. This is the teaching of Sri Caitanya Mahaprabhu:

"One should chant the holy name of the Lord in a humble state of mind, thinking oneself lower than the straw in the street. One should be more tolerant than a tree, devoid of all sense of false prestige and ready to offer all respects to others. In such a state of mind one can chant the holy name of the Lord constantly." A Vaisnava is always tolerant and submissive like trees and grass. He tolerates insults offered by others, for he is simply interested in chanting the holy name of the Lord without being disturbed.
