One should not think of personal loss or gain. “Krsna desires it, so I have to do it,” that’s all. There is no personal consideration. That is real Krsna consciousness. “Krsna, You are asking me to do this. I do not like to do this. You give me some other work.” That is not Krsna consciousness. There is no “yes” or “no.”
