The soul is the ray which in order to experience life needs this instrument: the vehicles of body and mind. The soul with its two vehicles, body and mind, could be called spirit-that other word we use for soul. Through the body it experiences outward conditions, through the mind it experiences inner conditions of life. So the soul experiences two spheres, the physical and the mental sphere: the mental sphere through the mind, and the physical sphere through the body with its five senses.
