I have, I own, an advantage over you, since I speak _de visu_, and that I strictly limit myself to interpret with exactitude the events with which my spiritual life is actually woven. But since you can see the possibility and probability of the scientific explanation of my statement, you cannot fail as you listen to increase your light and augment your knowledge. QUÆRENS. It is for this cause chiefly that I am always eager to hear you. LUMEN. Light, you understand, is the means of giving to the disincarnated soul _a direct vision_ of its planetary existences. [Sidenote: Constellations.] After having reviewed my earthly existence, I saw once more my life previous to my last one, upon one of the planets of Gamma in Virgo, light bringing to me the former only after 72 years, and the latter after 172 years. I see myself at present from Capella as I was upon the earth 72 years ago, and as I was upon Virgo 172 years ago. Thus two existences, both _past and successive_, are here shown me as _present and simultaneous_, by virtue of the laws of light which transmit them to me. [Sidenote: Andromeda.] [Sidenote: Effects of perspective.] Nearly five hundred years ago, I lived upon a world whose astronomical position as seen from the earth is precisely that of the left breast of Andromeda. Assuredly the inhabitants of that world do not suspect that the denizens of a little planet in space have joined the stars by fictitious lines, tracing figures of men, women, animals, and divers objects, incorporating all the stars in figures more or less original, in order to give them a name. It would greatly astonish some of these planetary people if they were told, that upon the Earth certain stars bear the names of Heart-of-the-Scorpion (what a heart!), Head-of-the-Dog, Tail-of-the-Great-Bear, Eye-of-the-Bull, Neck-of-the-Dragon, Brow-of-Capricorn. You are, of course, aware that neither the constellations drawn upon the celestial globe, nor the position of the stars upon that globe, are either real or absolute, but are only the result of the position of the Earth in space, and thus are simply a question of _perspective_. Go to the top of a mountain and fix upon a map the respective positions of all the summits surrounding you in that circular panorama, its hills, its valleys, its villages, its lakes; a map so constructed could only serve for the place from whence it was drawn. Now transport yourself ten miles farther; the same summits are visible, but their respective positions in regard to each other are different, resulting from the change in perspective. The panorama of the Alps and of the Oberland, as seen from Lucerne, and Pilatus does not in the least resemble that seen from the Fulkhorn, or from the Schynige Platte above Interlaken. Yet these are the same summits and the same lakes. It is exactly so with the stars. The same aspect is seen both from the star Delta in Andromeda and from the
