We are Kṛṣṇa-ites
Nectar of Devotion 14: A Kṛṣṇa conscious person, being naturally purified, has no need of developing any other purificatory process of thought or action. On account of his being highly elevated in Kṛṣṇa consciousness, he has already acquired all the good qualities and is following the rules and regulations prescribed for the mystic yogic process. Such rules are automatically practiced by the devotees. A concrete example is the quality of nonviolence, which is considered a good qualification. A devotee is naturally nonviolent and therefore doesn’t have to practice nonviolence separately. Some people seek purification by joining a vegetarian movement, but a devotee is automatically a vegetarian. He doesn’t need to practice separately in this matter or to join any society for vegetarians. He is automatically a vegetarian. There are many other instances showing that a devotee needn’t practice anything but Kṛṣṇa consciousness; all the good qualities of the demigods automatically develop within him. Those who are intentionally practicing to be vegetarians or to become nonviolent may have good qualifications by a material estimation, but these qualifications are not sufficient to make them devotees. A vegetarian is not necessarily a devotee, nor is a nonviolent person. But a devotee is automatically both vegetarian and nonviolent. We must conclude, therefore, that vegetarianism or nonviolence is not the cause of devotion.
Lecture on SB 6.1.17 — Honolulu, May 17, 1976: Similarly, our principle is that we are kind, merciful, to everyone. But we have to eat, so we eat Kṛṣṇa prasādam. Because after all, Kṛṣṇa is the Supreme Lord. So if He eats something, the responsibility is His. But we are not advocate of vegetarianism or nonvegetarianism. No. That is not our business. We are Kṛṣṇa-ites. What Kṛṣṇa said, we have to do. Therefore sādhu, suhṛt. Suhṛdaḥ sarva-bhūtānām. Sādhu is not enemy. Ajāta-śatrava. He does not create enemy, but the world is such that if you become devotee, even your father will be enemy.
So this vegetarianism is not a good position.
Prabhupāda: That. Then there is perfection, if you take Kṛṣṇa prasādam. Prasāde sarva-duḥkhānāṁ hānir asyopajāyate. So this is no good position.
