It is most remarkable that, while honestly confessing their entire ignorance of the true nature of even terrestrial matter—primordial substance being regarded more as a dream than as a sober reality—the Physicists should, nevertheless, set themselves up as judges of that matter, and claim to know what it is able and is not able to do, in various combinations. Scientists know this matter hardly skin‐deep, and yet they will dogmatize. It is “a mode of motion” and nothing else! But the “force” that is inherent in a living person’s breath, when blowing a speck of dust from the table, is also, undeniably, “a mode of motion.” It is as undeniably not a quality of the matter, or the particles of the speck, and it emanates from the living and thinking Entity that breathed, whether the impulse originated consciously or unconsciously. Indeed, to endow matter—something of which nothing is so far known—with an inherent quality called force, of the nature of which still less is known, is to create a far more serious difficulty than that which lies in the acceptation of the intervention of our “Nature‐Spirits” in every natural phenomenon. The Occultists—who, if they would express themselves correctly, do not say that matter, but only the _substance_ or _essence_ of matter, (_i.e._, Mûlaprakriti, the Root of all) is indestructible and eternal—assert that all the so‐called Forces of Nature, electricity, magnetism, light, heat, etc., etc., far from being modes of motion of material particles, are _in esse_, _i.e._, in their ultimate constitution, the differentiated aspects of that Universal Motion which is discussed and explained in the first pages of this volume. When Fohat is said to produce Seven Laya Centres, it means that, for formative or creative purposes, the _Great Law_—Theists may call it God—stays, or rather modifies, its perpetual motion on seven invisible points within the area of the Manifested Universe. “_The Great Breath digs through Space seven holes into Laya, to cause them to circumgyrate during Manvantara_,” says the Occult Catechism. We have said that Laya is what Science may call the zero‐point or line; the realm of absolute negativeness, or the one real absolute Force, the _noumenon_ of the Seventh State of that which we ignorantly call and recognize as “Force”; or again the noumenon of Undifferentiated Cosmic Substance, which is itself an unreachable and unknowable object for finite perception; the root and basis of all states of objectivity and also subjectivity; the neutral axis, not one of the many aspects, but its centre. It may serve to elucidate the meaning, if we try to imagine a “neutral centre”—the dream of those who would discover perpetual motion. A “neutral centre” is, in one aspect, the limiting point of any given set of senses. Thus, imagine two consecutive planes of matter; each of these corresponding to an appropriate set of perceptive organs. We are forced to admit that between
