Our Kṛṣṇa conscious practice . . . except mind, there are so many other things, just like anger, tongue, then jihvā-vegam, then udara-vegam. From tongue come little down. Udara means belly. The belly is already filled up; still I want to fill it more. That is called vegam, pushing of the belly. And when there are so much pushing of the tongue and pushing of the belly, the next underneath the genital, there is force of the genital. Then I require some sex. If I eat more, if I use my tongue unnecessarily, if I allow my mind to do anything and everything, then I cannot check my genital also. There will be sex urge which I cannot check. In this way there are so many pushings.
Rūpa Gosvāmī says one who has control over all this pushing machine, he can become spiritual master. Not that spiritual master is manufactured. One has to learn this, how to check the pushing of these things. Etān vegān yo viṣaheta dhīraḥ (NOI 1). One who can control over these pushing and remains dhīraḥ, steady, pṛthivīṁ sa śiṣyāt: he can make disciples all over the world. Open. Yes.
So everything depends on training. That is yoga system. Yoga means . . . the whole yoga system means training—our senses, our mind, our this, that, so many things—then we are fixed up in the self. Do you think that simply by fifteen minutes' meditation we realize? And do all nonsense all the day? No. It requires training. You are going to solve the problems of life, you want to do it very cheap? No. Then you'll be cheated. You have to pay for it. If you want the nicest thing, then you have to pay for it.
But by the grace of Lord Caitanya, the payment has been made very easy: chant Hare Kṛṣṇa. Everything becomes very . . . all this controlling system, perfection of yoga system, becomes very easy. That is the mercy of Lord Caitanya. Ihā haite sarva-siddhi haibe tomāra (Caitanya-bhāgavata Madhya 23.78).
Lord Caitanya has blessed that if you follow this principle, chanting, then you'll get all the perfection of self-realization. That is a fact.
So for this age, when people are so much fallen, no other process will be successful. This process is the only process. It is very easy and sublime and effective and practical, and one can realize oneself. Pratyakṣāvagamaṁ dharmyam (BG 9.2).
In the Bhagavad-gītā it is said that you can practically experience. In other system, you do not practically experience how far you are making progress. But this system, if you follow for a few days, you realize, "Yes, I am making progress." Just like if you eat, you understand that your hunger is satisfied. Similarly, actually if you follow this principle of Kṛṣṇa consciousness movement, you'll see yourself that you are advancing in the matter of self-realization.
