When you feel free you laught a lot, and about everything.
It's like jump from airplain.
In the begining you are afraid. But if you take a time to find that beyond your back there is parachute, this experiance of jumping become plesant, beyond fear.
When your morality is pure, you feel your self very light, and this lightly feeling make smile arise on your face.
There is no any enemy for you, no any attachement.
When attached beings are sad, freed beings are happy.
