The Destination of Faultfinders
Srila Bhaktisiddhanta Saraswati Thakur Prabhupada: Only those averse to Lord Hari and whose only assets are their defective material senses find fault with vaishnavas. Lord Krishna states in Bhagavad-gita 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 Krishna. 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. W* — From Amrta Vani, collected teachings of Srila Bhaktisiddhanta Saraswati Thakur.
