In wakefulness the eye of man sees at the utmost as far as one hour of distance(157) because through the instrumentality of the body the power of the spirit is thus determined; but with the inner sight and the mental eye it sees America, and it can perceive that which is there, and discover the conditions of things and organize affairs. If, then, the spirit were the same as the body, it would be necessary that the power of the inner sight should also be in the same proportion. Therefore, it is evident that this spirit is different from the body, and that the bird is different from the cage, and that the power and penetration of the spirit is stronger without the intermediary of the body. Now, if the instrument is abandoned, the possessor of the instrument continues to act. For example, if the pen is abandoned or broken, the writer remains living and present; if a house is ruined, the owner is alive and existing. This is one of the logical evidences for the immortality of the soul.
There is another: this body becomes weak or heavy or sick, or it finds health; it becomes tired or rested; sometimes the hand or leg is amputated, or its physical power is crippled; it becomes blind or deaf or dumb; its limbs may become paralyzed; briefly, the body may have all the imperfections. Nevertheless, the spirit in its original state, in its own spiritual perception, will be eternal and perpetual; it neither finds any imperfection, nor will it become crippled. But when the body is wholly subjected to disease and misfortune, it is deprived of the bounty of the spirit, like a mirror which, when it becomes broken or dirty or dusty, cannot reflect the rays of the sun nor any longer show its bounties.
We have already explained that the spirit of man is not in the body because it is freed and sanctified from entrance and exit, which are bodily conditions. The connection of the spirit with the body is like that of the sun with the mirror. Briefly, the human spirit is in one condition. It neither becomes ill from the diseases of the body nor cured by its health; it does not become sick, nor weak, nor miserable, nor poor, nor light, nor small—that is to say, it will not be injured because of the infirmities of the body, and no effect will be visible even if the body becomes weak, or if the hands and feet and tongue be cut off, or if it loses the power of hearing or sight. Therefore, it is evident and certain that the spirit is different from the body, and that its duration is independent of that of the body; on the contrary, the spirit with the utmost greatness rules in the world of the body; and its power and influence, like the bounty of the sun in the mirror, are apparent and visible. But when the mirror becomes dusty or breaks, it will cease to reflect the rays of the sun.
