"A Vaiṣṇava, or devotee of Lord, his life is dedicated for the benefit of the people. You know—most of you belong to Christian community—how Lord Jesus Christ, he said that for your sinful activities he has sacrificed himself. That is the determination of devotee of the Lord. They don't care for personal comforts. Because they love Kṛṣṇa or God, therefore they love all living entities because all living entities are in relationship with Kṛṣṇa. So similarly you should learn. This Kṛṣṇa consciousness movement means to become Vaiṣṇava and feel for the suffering humanity."
(Srila Prabhupada Lecture, Los Angeles, December 9, 1968)
