I just want you to think for a second, what is joy?
How do you know when you have it?
How does it feel in your mind, your heart, your body,?
Just put your hand over your heart, take a few deep breaths, and just imagine joy. Just imagine what that is. You may have some recollection of when you last had it.
What created it? You can bring this up anytime you like, so there's no excuse to not have it. Or is there?
