There is a big list of vairagya: "You cannot do this, you cannot do this, you cannot do this, you cannot do this..." And the whole list is summarized that "You cannot have any illicit connection with woman, you cannot eat any nonvegetarian dish, you cannot be addicted, any kind of intoxication, and you cannot take part in any kind of gambling." At least these four things... These four things include everything, all kinds of vairagya. So we have to test how much we have been able to discard these things. Then vairagya. Then I can control my mind. Controlling mind is not so easy thing that I go to the store and purchase something. No. Abhyasena tu kaunteya vairagyena ca grhyate [BG 6.35]. So this vairagya can be very easily practiced when you are in Krsna consciousness.
