But never mind there is any discomfort of the body. We shall not be very much concerned for that. Devotee means he is able to tolerate all kinds of discomfort and whims of the material nature, and because he is so much absorbed in serving Krishna, he takes no time to become angry or take offense with others or find out some fault, no. Devotee means very liberal and kind to everyone, always gentleman under all kinds of conditions of life.
