Successful means that you haven't got to accept any more this material body. You will get a spiritual body and go to Kṛṣṇa, or go to home, go to back to Godhead. So if you increase your attachment for Kṛṣṇa, the benefit is that you make a solution for all the problems of life. It is scientific. Mayy āsakta manāḥ pārtha.
So in the beginning, in order to increase your attachment for Kṛṣṇa, you have to follow the regulative principles, "Don't do this." Just like a doctor gives you prescription, "Don't eat this. Don't do this," similarly, there are so many dont’s and so many do’s. So we have to accept the do’s, not the dont’s. Ānukūlyena kṛṣṇānu-śīlanam (CC Madhya 19.167). This is called favorably cultivating Kṛṣṇa consciousness. We have to accept the do’s, not the dont’s.
Ānukūlyasya saṅkalpa, ānukūlyena kṛṣṇānuśīlanam. We have to accept the favorable things. So if illicit sex life is unfavorable for my advancement in Kṛṣṇa consciousness, I must accept it. You cannot argue. That will not help you. Similarly, intoxication. Similarly, meat-eating. Similarly, gambling. Because these are the four pillars of sinful life: illicit sex, meat-eating, intoxication and gambling. The roof of sinful life is held by these four pillars.
So these four pillars, in the beginning of Kṛṣṇa consciousness, when you are actually going to take Kṛṣṇa consciousness seriously . . . just like some souls will be initiated today. This means that he is going to take Kṛṣṇa consciousness very serious. So one who is serious to take Kṛṣṇa consciousness, his first business is to break these four pillars of sinful life so there will be no chance of sin. Kṛṣṇa says in the Bhagavad-gītā, yeṣāṁ anta-gataṁ pāpam: "One who is freed from all sinful reaction of life . . ." Yeṣāṁ anta-gataṁ pāpaṁ janānāṁ puṇya-karmaṇām. Puṇya-karmaṇām, pious activities. "Those who are acting in pious life, simply executing pious activities . . ."
Pious activities means yajña-dāna-tapa-kriyā. Pious activities means yajña, performing yajña. Just like there will be fire sacrifice; dāna, charity, giving charity for Kṛṣṇa's propaganda. The Kṛṣṇa consciousness movement is making propaganda, so they require money. Money is Kṛṣṇa's monies. Everyone is holding Kṛṣṇa's money. So the sooner they spare that money . . .
Because if I am holding your money, if I give it to you, then I become released from my criminal activities. Suppose I have stolen something from your pocket and I become conscious, "So this stealing is not good," so as soon as I return unto you, "Please take this money; I was mistaken," so thing is settled up. But if you hold it, then you are criminal. You will be punished.
