“A transmigration of the same particles of spirits from a lower to a higher organization, is demonstrated from the fact that the same particles exist in a diffused scattered state, mingled with other matter; next, they exist in a united form, growing out of the earth in the shape of grass, herbs, and trees; and after this, these vegetables become food for celestial animals, and these same particles are organized into their offspring, and thus form the spirits of animals. Here then, is apparently a transmigration of the same particles of spirit from an inferior to a superior organization, wherein their condition is improved, and their sphere of action enlarged. Who shall set any bounds to this upward tendency of spirit? Who shall prescribe limits to its progress? If it abide the laws and conditions of its several states of existence, who shall say that it will not progress until it shall gain the very summit of perfection, and exist in all the glorious beauty of the image of God?”
