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. PERFECTION IS ENDLESS Know that the conditions of existence are limited to the conditions of servitude, of prophethood, and of Deity, but the divine and the contingent perfections are unlimited. When you reflect deeply, you discover that also outwardly the perfections of existence are also unlimited, for you cannot find a being so perfect that you cannot imagine a superior one. For example, you cannot see a ruby in the mineral kingdom, a rose in the vegetable kingdom, or a nightingale in the animal kingdom, without imagining that there might be better specimens. As the divine bounties are endless, so human perfections are endless. If it were possible to reach a limit of perfection, then one of the realities of the beings might reach the condition of being independent of God, and the contingent might attain to the condition of the absolute. But for every being there is a point which it cannot overpass; that is to say, he who is in the condition of servitude, however far he may progress in gaining limitless perfections, will never reach the condition of Deity. It is the same with the other beings: a mineral, however far it may progress in the mineral kingdom, cannot gain the vegetable power; also in a flower, however far it may progress in the vegetable kingdom, no power of the senses will appear. So this silver mineral cannot gain hearing or sight; it can only improve in its own condition, and become a perfect mineral, but it cannot acquire the power of growth, or the power of sensation, or attain to life; it can only progress in its own condition.
