Only those averse to Lord Hari and whose only assets are their defective material senses find fault with Vaisnavas. In Bhagavad-gita Lord Krsna states that His devotees never perish. Can those who worship the Lord without deviation ever fall down? They certainly achieve perfection. Since our vision is polluted we find fault with others and thereby ruin ourselves. When we thus become materialists we become bereft of service to guru and Krsna. We think of the trouble of others because we ourselves are in trouble. Because we are full of faults we find fault with others. If we can correct ourselves, we will find that we have no time to find fault with others.
