This great power must evidently be differentiated from the physical body or temple in which it is manifested. Observe and understand how this human body changes; nevertheless, the spirit of man remains ever in the same condition. For instance, the body sometimes grows weak, it becomes strong or stout, sometimes it grows smaller or may be dismembered, but there is no effect upon the spirit. The eye may become blind, the foot may be amputated, but no imperfection afflicts the spirit. This is proof that the spirit of man is distinct from his body. Defects in the body or its members do not imply defects in the spirit. This leads to the accurate conclusion that if the whole body should be subjected to a radical change, the spirit will survive that change; that even if the body of man is destroyed and becomes nonexistent, the spirit of man remains unaffected. For the spirit of man is everlasting. Sometimes the body sleeps, the eyes do not see, the ears do not hear, the members cease to act, every function is as inactive as death; nevertheless, the spirit sees, hears and soars on high. For it is possessed of these faculties which operate without the instrumentality of the body. In the world of thought it sees without eyes, hears without ears and travels without the motion of foot. Without physical force it exercises every function. This makes it evident that during sleep the spirit is alive though the body is as dead. In the world of dreams the body becomes absolutely passive, but the spirit still functions actively, possessed of all susceptibilities. This leads to the conclusion that the life of the spirit is neither conditional nor dependent upon the life of the body. At most it can be said that the body is a mere garment utilized by the spirit. If that garment be destroyed, the wearer is not affected but is, in fact, protected.
