You want to be happy, and you try as best you can to achieve happiness. You just do not know how. You make mistakes. You have made some unwholesome choices —perhaps many. You have harbored ill will. You have hurt others.
You think you cannot change, that your ways are set. But sooner or later, you realize that your approach has not worked as desired, that it is not working, that it will never work.
And when you recognize this truth, change is inevitable. This is the dawn of wisdom. It is your nature.
The very same compulsion that led you to act in unwholesome ways will lead you to try a different approach. This is compassion —for yourself and for all.
