pantheistic sense; and the Occultists, while accepting this thought for convenience sake, distinguish the progressive stages of the evolution of the concrete from the abstract, by terms of which the “Mineral, Vegetable, Animal Monad,” etc., are examples. The term merely means that the tidal wave of spiritual evolution is passing through that arc of its circuit. The “Monadic Essence” begins to imperceptibly differentiate towards individual consciousness in the vegetable kingdom. As the Monads are uncompounded things, as correctly defined by Leibnitz, it is the Spiritual Essence which vivifies them in their degrees of differentiation, which properly constitutes the Monad—not the atomic aggregation, which is only the vehicle and the substance through which thrill the lower and the higher degrees of intelligence.(293) Leibnitz conceived of the Monads as elementary and indestructible units, endowed with the power of _giving and receiving_ with respect to other units, and thus of determining all spiritual and physical phenomena. It is he who invented the term apperception, which together with nerve‐ (not perception, but rather) sensation, expresses the state of the Monadic consciousness through all the kingdoms up to Man. Thus it may be wrong, on strictly metaphysical lines, to call Âtmâ‐Buddhi a Monad, since in the materialistic view it is dual and therefore compound. But as Matter is Spirit, and _vice versâ_; and since the Universe and the Deity which informs it are unthinkable apart from each other; so in the case of Âtmâ‐Buddhi. The latter being the vehicle of the former, Buddhi stands in the same relation to Âtmâ, as Adam‐Kadmon, the Kabalistic Logos, does to Ain Suph, or Mûlaprakriti to Parabrahman. And now a few words more on the Moon. What, it may be asked, are the “Lunar Monads,” just spoken of? The description of the seven Classes of Pitris will come later, but now some general explanations may be given. It must be plain to everyone that they are Monads, who, having ended their Life‐Cycle on the Lunar Chain, which is inferior to the Terrestrial Chain, have incarnated on the latter. But there are some further details which may be added, though they border too closely on forbidden ground to be treated of fully. The last word of the mystery is divulged only to Adepts, but it may be stated that our satellite is only the gross body of its invisible principles. Seeing then that there are seven Earths, so there are seven Moons, the last alone being visible; the same for the Sun, whose visible body is called a Mâyâ, a reflection, just as man’s body is. “_The real Sun and the real Moon are as invisible as the real man_,” says an Occult maxim.
