Dina-bandhu
Srimad-Bhagavatam
SB Canto 4
SB 4.12.51, Purport:
Pure devotees, out of compassion for the fallen souls, are kṛpālu, very kind to people in general; they distribute this Bhāgavata knowledge all over the world. A kindhearted devotee is called dīna-nātha, protector of the poor, ignorant mass of people. Lord Kṛṣṇa is also known as dīna-nātha or dīna-bandhu, the master or actual friend of the poor living entities, and His pure devotee also takes the same position of dīna-nātha.
