The saying "no self, no problem" probably comes from Zen. In their cultures, where Buddhism is kind of taken for granted, as well as karma, causality, former and future life, and the possibility for becoming enlightened, then it's safe to skirt the danger of nihilism, which would be, I don't exist because Buddha said I have no self, and therefore I have no problem because I don't exist. That would be a bad misunderstanding. But in those cultures, it would not be as easy to have that understanding as it would be here in the west, where we really are nihilistic.

Take the example of people who are being most unrealistic - people who are beating monks to death and torturing them. Why shouldn't you be angry or hate that person? Well, the person who is doing that is very unhappy. They are being ordered by a higher-up.

Those caught in the cycle of self-concern suffer helplessly, while the compassionate are more free and, implicitly, more happy.

In Buddhism, we say reincarnation is the conscious taking of rebirth by a Bodhisattva, or by a high being, whereas rebirth, is what most people do. Rebirth is an involuntary process where they seek traction by finding a new body after their subtle mind loses the old one. There are two things commonly said about this. One- there is no evidence for it and two- if there is evidence, what's the mechanism which carries the consciousness from one life to another.

In Buddhist ideology, the conventional self is that which is constructed in a way by the use of the pronoun, and when you realize there is no absolute ego there, no disconnected one, self, or ego, then that actually strengthens your conventional ego. It does so in the sense that then you realize it's a construction, and you can strengthen it in order to help others, or do whatever you're trying to do, it's not like you no longer know who you are. Then you can organize your behavior by using your ego, as it's now the pronoun.

First of all, "no self" doesn't mean there is no self, haha. So the "no problem" is jumped at a little too fast I'm afraid. Especially in American culture where people tend to be materialistic philosophically. I don't mean running to the mall, but philosophically, you see?

Commercial interests with their advertising industry do not want people to develop contentment and less greed. Military interests in economic, political, ethnic or nationalist guises, do not want people to develop more tolerance, nonviolence and compassion. And ruling groups in general, in whatever sort of hierarchy do not want the ruled to become too insightful, too independent, too creative on their own, as the danger is that they will become insubordinate, rebellious, and unproductive in their alloted tasks.
