"The devotees are actually saintly persons, or sādhus. The first qualification of a sādhu, or devotee, is ahiṁsā, or nonviolence. Persons interested in the path of devotional service, or in going back home, back to Godhead, must first practice ahiṁsā, or nonviolence. A sādhu is described as titikṣavaḥ kāruṇikāḥ (SB 3.25.21). A devotee should be tolerant and should be very much compassionate toward others. For example, if he suffers personal injury, he should tolerate it, but if someone else suffers injury, the devotee need not tolerate it. The whole world is full of violence, and a devotee's first business is to stop this violence, including the unnecessary slaughter of animals. 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. Suhṛdaḥ sarva-dehinām: a true devotee is the friend of all living entities. Kṛṣṇa claims in Bhagavad-gītā to be the father of all species of living entities; consequently the devotee of Kṛṣṇa is always a friend of all. This is called ahiṁsā. Such nonviolence can be practiced only when we follow in the footsteps of great ācāryas."
