"In our inner world, we go on avoiding problems which we cannot solve. We try to forget problems which we cannot solve, and we begin to focus our mind on problems which we can solve. Because of that, your chief diseases go underground. Ultimately, you are not even aware of them, and you go on fighting with phony problems which are not real problems. These phony problems take much energy and dissipate your energies, destroy them, and you remain the same because you go on fighting with the leaves."
