SECOND SOURCE: This is objective. That is to say, it is a sort of empirical judgement which has been formed through repeated observations and numerous occurrences of events. Indeed, when it is understood that a single spirit continues after death, this necessitates the continuation of all spirits as a category of being. For according to the science of logic it is certain that if an intrinsic quality is observed in a single individual, the existence of that quality may be assumed in all individuals. Because it is intrinsic. If it is intrinsic, it will be present in each individual. Whereas the indications based on not one but on innumerable observations beyond calculation and count, and the signs pointing to the immortality of spirits are so definite, that like for us there is a place called the New World, that is, America, and that human beings are found there, we can in no way doubt the existence of those people. In the same way, it is unacceptable to doubt that the spirits of those who have died are now present in great numbers in the World of the Inner Dimension of Things and in the Spirit World, and that they have relations with us. Our immaterial gifts go to them, and their luminous emanations come to us.

Moreover, with certain intuition, one may perceive with one's conscience that a fundamental aspect of man continues after his death. And that fundamental aspect is spirit. As for spirit, it is not subject to destruction and dissolution. This is because it is simple and uncompounded, it has unity. As for destruction, dissolution, and decomposition, they are the function of complex and compound substances. As we explained above, life ensures a form of unity within multiplicity; it causes a sort of permanence. That is to say, unity and permanence are fundamental to spirit, from which they spread to multiplicity.

The mortality of man's spirit would be either through destruction and dissolution, whereas unity provides no opportunity for these, and its simple nature disallows decomposition; or it would be through annihilation. But the limitless compassion of the Absolutely Generous One would not permit annihilation, and His boundless munificence would not allow that He should take back from the human spirit the bounty of existence which He has bestowed on it, which it ardently desires, and of which it is worthy.

THIRD SOURCE: Man's spirit, which has been clothed in a living, conscious, luminous external existence, is a comprehensive and veracious commanding law disposed to acquiring universality. And even the weakest commanding laws manifest stability and permanence. For if it is considered carefully, it will be seen that present in all species which are subject to change, is a constant truth that, revolving within the changes, transformations, and stages of life, causes the outer forms of things to change, and living and not dying, is permanent.
