    The Metaphysical Encyclopedia of two volumes was written by a real necessity for every concerned person to be informed of the real Truth that is contained in the immense area of the invisible world. It is offered with the the same love and the same frankness for every metaphysical or antimetaphysical being who will wish to know the other world, that is extended beyond the natural one, beyond our physical dimension.
    As described, this invisible world that is incredibly huge, supports our known visible world, as a docked pyramid and it offers it not only substance and life, but also its great care, in order to keep him proper for his destination, meaning to train the humansouls that are bodyborned within him.
    The present variegated litterature of the irresponsible theories on the sacred Metaphysics, has obliged the writer to write and to present in only two volumes, nearly in summary, the most substantial points of the Metaphysics, so as to keep informed the young people who try to find a correct, pure and honest orientation, in this subject of ours.
