A question arises: How does this take place, how does it happen? And the answer is that there is a magnetic action between the person and the mask. It is the strength of the physical body which holds the spirit, and it is the strength of the spirit which holds the body. The physical body holds on to the spirit because it only lives by the life of the spirit, and without the spirit it is dead. And as every being, however small, struggles for life, this physical body tries to hold on to the spirit; and it does so to the last, as someone who is on the point of losing his gold might hold it tightly in his hand until his hand is paralyzed, and he can no longer hold it and so lets it drop. It does not mean he does not want it; it only means he cannot hold it any longer. And so it is with the spirit; as long as the spirit is interested in the physical body it holds it, permeates it, and embraces it. But as soon as it feels that it does not want it any more, that it no longer has any use for the body, it drops it.
