Well, I guess that conclusion could appear easily, especially if you believe in western take on karma. What westerners believe to be karma could be summed up as the law of reflection. In case of law of reflection if you use too much energy which then isn't spent on the working itself, it then returns back to us with whatever it is dragging. To avoid this problem one should either limit the energy output or use some protection mechanism (succubi and avatars are a good choice for this one).
