The heart is just the heart; thoughts and feelings are just thoughts and feelings. Let things be just as they are.
Ajahn ChahJust know what is happening in your mind - not happy or sad about it, not attached. If you suffer see it, know it, and be empty. It's like a letter - you have to open it before you can know what's in it.
Ajahn ChahA woman wanted to know how to deal with anger. I asked when anger arose whose anger it was. She said it was hers. Well, if it really was her anger, then she should be able to tell it to go away, shouldnt she? But it really isn't hers to command. Holding on to anger as a personal possession will cause suffering. If anger really belonged to us, it would have to obey us. If it doesn't obey us, that means it's only a deception. Don't fall for it. Whenever the mind is happy or sad, don't fall for it. Its all a deception.
