The New Testament tells us that we possess an incorruptible body of pure light, which we call the body of glory. In the very distant past, this body enabled human beings to travel through space and to see and understand the whole of creation. But as they became more and more deeply immersed in the denser layers of matter, humans neglected their body of glory until it became incapable of manifesting itself; and now we have to reverse this movement and nourish and care for it so that it can be restored to its former function.
It is thanks to our body of glory, after all, that we shall live eternally and recapture the powers that were ours in the past: one day, the animals will obey us and the spirits serve us once again. All the forces of creation are at the disposal of those who nourish their body of glory until it attains its full stature, for it is in this glorious body, not in our physical body, that God dwells.
