If we want to control the mind, then we have to adopt these regulative principles of life. Not that we have to give up, but we have to make regulated. Vairagya. Then it will be possible to adopt. And the best thing is that engage your mind always in Krsna consciousness. We are trying to engage our students twenty-four hours either in this way or that way, this way or that way, in Krsna consciousness. That is samadhi, trance, transcendental situation. You can eat, you can enjoy, you can dance, you can see, you can work - all things for Krsna consciousness. That will automatically make you renounced order of life. But if you try to follow this yoga system which was possible in the Satya-yuga some millions of years before, and if you want to adopt that, oh, it is not possible.
