.. once you master every single part of your physical body with your will power, you may dress your physical body with your spiritual body. Meaning: your spiritual body is then no longer imprisoned in your physical body; instead you pull your spiritual body over the physical. Then physical laws like time and space do not apply anymore. You can then fly even to Heaven without wings, just with your will. The condition for such powers is, that a person is completely in charge: that the will power controls, not the desires.
