Prabhupāda: If we follow those principles, then we can work or we can go to the perfection of Kṛṣṇa consciousness movement. It is not the method that is important. The real important is how to develop your love of Kṛṣṇa. If somebody develops love of Kṛṣṇa, or God, without those methods, there is no objection. We are not limited by the methods or ritualistic methods. But there are certain ritualistic method, which, if one follows, then he can quickly learn the art of Kṛṣṇa consciousness. Just like we restrict our students in four principles: illicit sex life and intoxication, gambling, and meat-eating. So it is not that a gambler or a meat-eater or a man addicted to illicit sex life, he cannot love Kṛṣṇa. It is not that. But that is very rare case. If he follows these principles, then it will be easier for him. Because Kṛṣṇa, or God is pure, so so long one is impure in his habits, it is not possible for him. So these are the purificatory processes.
