It used to be thought that the soul fought with the body until one would conquer the other with force.
Then the Balance Shem Tov (founder of Hassidism) came and taught a new path :
The body too could come to appreciate what the soul desires.
In the place of self affliction and fasting he introduced the path of meditations and joy.
Every need of the body, he taught, could provide a channel to carry the soul.
