Pure devotees, out of compassion for the fallen souls, are krpalu, very kind to people in general; they distribute this Bhagavata knowledge all over the world. A kindhearted devotee is called dina-natha, protector of the poor, ignorant mass of people. Lord Krsna is also known as dina-natha or dina-bandhu, the master or actual friend of the poor living entities, and His pure devotee also takes the same position of dina-natha.
