Man is only free once he frees himself of desire. Although a paradox, desire is lined with hope and motive, thus caging it by limitation. Learning about freedom is about letting go of desire so the essence can prevail, because to the essence desire is meaningless. 

For the man doesn’t require desire, instead essence is required. Desire requires essence in order to be desired, but desire is not necessary for the essence, since the essence simply is. When man learns to overcome desire and parts with it, man has learned to master himself.
