A pure devotee of the Supreme Personality of Godhead is always thinking of how fallen, conditioned souls can be delivered. The Supreme Personality of Godhead, influenced by the devotees' attempt to deliver fallen souls, enlightens the people in general from within by His causeless mercy.
Due to so-called improvements in material opulence, people have entirely given up the path of realization. Practically no one is interested in God, one's relationship with God or how one should act. Modern men have altogether forgotten such questions because they are mad.
Just as fire applied to gold removes any discoloration caused by traces of other metals, Lord Vishnu within the heart purifies the minds of the yogis.
A devotee is the friend not only of human society but of all living entities, for he sees all living entities as sons of the Supreme Personality of Godhead. He does not claim himself to be the only son of God and allow all others to be killed, thinking that they have no soul. This kind of philosophy is never advocated by a pure devotee of the Lord.
