"Do not give the ingredients for sense enjoyment "

Prabhupāda: No, no. By controlling the senses, gradually the mind will be controlled. You know. In the..., the tiger and the lion trained up to play in the circus, do you know how it is done?

Dhanañjaya: They starve the animals. 

Prabhupāda: No.

Puṣṭa-kṛṣṇa: They feed them every time, whenever they do something. 

Prabhupāda: No, after catching them from the forest, they kept within the bars, and no eating for at least one week. Then the trainer comes. Only whips. He comes, and open the doors and only: (makes sound) Flosh, flosh, flosh. So already he's hungry, weak, and he's whipped. In this way, he becomes fearful. As soon as the man comes, he becomes fearful. Then he gives him little food. In this way, after all it is animal, he thinks that "This man is my God. He can save me. He can kill me." Then he takes to him. Whatever he says, he takes. Similarly, if you do not give the ingredients for sense enjoyment, the mind will be controlled. 

That is the beginning. You simply... Don't give... The mind wants, "Now let me go to the restaurant." "No, sir." Beat him with shoes. Instead of going to the restaurant, he beats the mind with shoes. Then mind will not again say, "Go to the restaurant." That is called swami, gosvāmī. One who can control his mind, that is gosvāmī. We giving the title "Gosvāmī" But if you cannot control your mind, then you are unfit. Go means senses, and svāmī means master. One who can control the senses and master, he is gosvāmī. (pause) ...definition of gosvāmī there: vāco vegaṁ krodha-vegaṁ manasa-vegam udara-vegam upastha-vegam, etān vegān yo viṣaheta dhīraḥ pṛthivīṁ sa śiṣyāt [NoI 1]. You have to control the impulse of speaking, vāco vegam, the impulse of becoming angry, vāco vegam, krodha-vegam. Then manasa-vegam, force of the mind. Then udara-vegam, the belly. Belly, already, although it is filled up, and as soon as there is some nice... Please fill up again, again. This you have to control, udara-vegam. Udaropastha-vegam, genital. In this way, one who has controlled all these forces, he is able to make disciple all over the world. Otherwise, not this rascal guru. As soon as he saw one very beautiful secretary, "Oh, let me enjoy." And he's guru. So these are cheating. And people want to be cheated. Therefore the cheaters are there.
