Look at children. Of course they may quarrel, but generally speaking they do not harbor ill feelings as much or as long as adults do. Most adults have the advantage of education over children, but what is the use of an education if they show a big smile while hiding negative feelings deep inside? Children dont usually act in such a manner. If they feel angry with someone, they express it, and then it is finished. They can still play with that person the following day.
I think that I do feel that my nature is to express what this self, this particular self at this time, experiences in the world. And that is so organic - I use this metaphor a lot but I'll use it again - it's like a pine tree producing pine cones, or a blackberry bush producing blackberries - it's just what happens with this being, now.
