Athanasius, you're welcome. Had meant to put emphasis on the negative to stress my opinion that it is generally overlooked, avoided, and denied more in general than by you. There is a tendency, I think to stress the positive, look on the bright side, etc, that may have many good points, but which preclude the kind of cleansing I was talking about.
SirFshAlot, In the case you described, "but what if you aren't content with yourself, because of the forces that drive you?", It is a question og feeling those forces. I would guess that they are the voices of a parent, parents, telling you that in some way you don't measure up, or some such negative voice from long ago. Our vague feelings of discontent have some such origin. Anyway I think we made up our minds never to feel again as bad as we once were easily made to feel, and so we have defenses like anger and hostility to anything that tries or threatens to make us feel those feelings again.
But if one can drop the defense and allow the feelings in, they can become intense enough to be just like they once were, and what that does is take you right back with memory of the past. After such an experience, it is a little more difficult to believe in negative lies about yourself. Even just understanding that something like this is happening can help. So the trick is to realize that the problem is not that you need to be better, but that your need to stop believing that you need to be better. With no hidden feelings of inadequacy to defend against, it's easer to be better, it just happens without striving. The key is learning to feel what we really feel, that we are worthless, and see that that is a lie.
