In the true order of things one does not do something in order to be happy-one is happy and, hence, does something. One does not do some things in order to be compassionate, one is compassionate and, hence, acts in a certain way.

Release the joy that is inside of another, and you release the joy that is inside of you.

It is you who are choosing, in any moment, to be happy or choosing to be sad, or choosing to be angry, or forgiving, or enlightened, or whatever. You are choosing.

A person can either do something in order to be happy, or... a person can start the day by simply deciding to BE happy and the things that person will do will automatically reflect that.
