Life in the world of the genius is longer compared with life on the physical plane. It is this life which may be called the life in the hereafter. But there comes a time when all that was borrowed from the plane of the genius has to be given back to that plane too, for it did not belong to the soul. It is according to the same theory that our body will not have what does not belong to it; it will throw it out or, if the body cannot throw it out, it will be thrown out of life. So no one can carry the substance of another plane beyond. Each substance has its own plane and must be returned to that plane. This is the only way the soul can be freed from that plane in order to rise above it.
