Devotee (2): What are the senses?
Devotee (1): "What are the senses, how to control the things to be done?"
Prabhupāda: Senses, everyone knows. You see. How we are seeing? Through the sense of eyes. These are senses. Sense organs. You can touch with the hand. These are sense organs. You can hear about some knowledge. That is sense organ. You can taste one fruit. These are senses. Is it very difficult to understand? You have got these senses. By some senses, you are acquiring knowledge, and some senses you are working. There are five senses for acquiring knowledge, and five senses for working. These are senses.
Devotee (1): "How to control them? What are the things to be done?"
Prabhupāda: Yes. Control. It is very difficult. To control. But if you put it under the control of the Supreme, it will be controlled. You want to see very beautiful thing. But if you engage your seeing power on the most beautiful, Kṛṣṇa, then you forget, other things. This is sense control. You are going to restaurant to enjoy your tongue, but if you take kṛṣṇa-prasādam, then you'll forget going to restaurant. This is sense control. Sense control means to engage the senses in the service of Kṛṣṇa. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170). Simply we have to purify the senses. The senses must be there. Otherwise, I am not a living being. I am stone. But at the present moment, I am misguided. I am using my senses for other purposes than Kṛṣṇa's. Therefore I cannot control. And as soon as you apply your senses for satisfying Kṛṣṇa, then they are controlled, automatically.
Devotee(1): (reading question) "What are your views about silent meditation on one's, in one's own self, and this japa, gāyatrī-mantra?"
Prabhupāda: Yes. Simply by mechanical japa, we'll not be ha... We have to hear from the śāstra what is self. Of course, those who are actually following the rules and regulation of gāyatrī-mantra, they'll be, gradually come to the spiritual understanding. But not as official chanting. That will not help. "Because I have got gāyatrī-mantra, oh, om-burble bura burra..." (makes sound) Finish. Not like that. Don't cheat yourself. Try to understand.
