3. OF THE SEVEN(253)—FIRST ONE MANIFESTED, SIX CONCEALED; TWO MANIFESTED, FIVE CONCEALED; THREE MANIFESTED, FOUR CONCEALED; FOUR PRODUCED, THREE HIDDEN; FOUR AND ONE TSAN(254) REVEALED, TWO AND ONE HALF CONCEALED; SIX TO BE MANIFESTED, ONE LAID ASIDE (_a_). LASTLY, SEVEN SMALL WHEELS REVOLVING; ONE GIVING BIRTH TO THE OTHER (_b_). (_a_) Although these Stanzas refer to the whole Universe after a Mahâpralaya (Universal Dissolution), yet this sentence, as any student of Occultism may see, refers also by analogy to the evolution and final formation of the primitive (though compound) seven Elements on our Earth. Of these, four Elements are now fully manifested, while the fifth—Ether—is only partially so, as we are hardly in the second half of the Fourth Round, and consequently the fifth Element will manifest fully only in the Fifth Round. The Worlds, including our own, as germs, were of course primarily evolved from the One Element in its second stage—“Father‐ Mother,” the Differentiated World’s Soul, not what is termed the “Over‐ Soul” by Emerson—whether we call it, with Modern Science, cosmic dust and fire‐mist, or with Occultism, Âkâsha, Jîvâtmâ, Divine Astral Light, or the “Soul of the World.” But this first stage of Evolution was in due course of time followed by the next. No World, and no heavenly body, could be constructed on the objective plane, had not the Elements been already sufficiently differentiated from their primeval Ilus, resting in Laya. The latter term is a synonym of Nirvâna. It is, in fact, the Nirvânic dissociation of all substances, merged after a Life‐Cycle into the latency of their primary conditions. It is the luminous but bodiless shadow of the Matter that _was_, the realm of negativeness—wherein lie latent during their period of rest the active Forces of the Universe. Now, speaking of Elements, it is made the standing reproach of the Ancients, that they “supposed their elements simple and undecomposable.” The shades of our pre‐historic ancestors might return the compliment to modern Physicists, now that new discoveries in Chemistry have led Mr. W. Crookes, F.R.S., to admit, that Science is yet a thousand leagues from a knowledge of the compound nature of the simplest molecule. From him we learn that such a thing as a really simple molecule entirely homogeneous is _terra incognita_ in Chemistry. “Where are we to draw the line?” he asks; “is there no way out of this perplexity? Must we either make the elementary examinations so stiff that only 60 or 70 candidates can pass, or must we open the examination doors so wide that the number of admissions is limited only by the number of applicants?” And then the learned chemist gives striking instances. He says:
