Suppose there is very nice performance of sense gratification, and one wants to go there. But if you can control your senses—"No, not to go there. Come here in this storefront. Hear Bhagavad-gītā," then you become master. You become master. That is svami. In similar way, if you can control your all your senses . . . now, the sense gratification . . . the most important task for controlling the sense is the tongue. I have several times explained that the tongue is the beginning of all senses. So if you can control the tongue, then you can control other senses also. And if you cannot control the tongue, then you cannot control other senses. So you should begin controlling the senses.
The tongue has two functions—to taste and to vibrate. Vibrate Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare / Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare and taste kṛṣṇa-prasāda. Just see how you are making advancement. This is called damaḥ. So as soon as you are able to control your senses, naturally you shall be able to control your mind. That is called śamaḥ.
