The soul is the greening life force of the flesh, for the body grows and prospers through her, just as the earth becomes fruitful when it is moistened. The soul humidifies the body so it does not dry out, just like the rain which soaks into the earth.
So long as we do not die to ourselves, and so long as we are identified with someone or something, we shall never be free. The spiritual way is not for those wrapped up in exterior life.
