The student of occultism, particularly at the beginning of his studies, experiences difficulty in comprehending just what is meant by the term "plane" as employed in the occult teachings. His first impression, usually encouraged by the use of the dictionary, is that each "plane" is one of a series of strata or layers, above and below which are present other layers or strata. Even after the student progresses in his understanding of the subject, this original picture of material layers and strata tends to persist in his thought on the subject. The error, of course, arises from his original conception of the planes, layers, or strata as being composed of gross material matter, whereas, as a matter of fact, only one of the many planes is so composed. When one stops to think that even the grossest form of matter is itself composed of vibrations of energy (for science teaches that all matter is but energy at the last); and that all other forms of material substance is likewise so composed of vibrations of energy; then one is on the road to the discovery of the real state of affairs. Then he begins to realize that instead of the planes of being rising one above the other in the scale of their fineness, they are graded according to their degree of vibratory energy, and each may actually occupy the same space as all the others. In short, the "planes" are not strata or layers of "matter" at all, but are simply different states of vibration of energy; and that which we know as "matter" is simply one (and a very low one) of the many forms of such vibrations. From the above, it is seen that the various planes of being are not distinguished by spatial position; they do not lie one superimposed on the other, like layers or strata of matter. Instead, they interpenetrate each other in the same limits of space. A single point of space may accommodate the manifestations of each and all of the seven great planes of being, and all the subdivisions, and sub-divisions (sevenfold in division) at the same time. The old occultists impressed this and other facts upon the minds of their pupils by the oft-repeated aphorism: "A PLANE OF BEING IS NOT A PLACE OF BEING, BUT A STATE OF BEING." And the "state of being" is simply a certain manifestation of vibratory energy. With these ideas firmly fixed in the mind, the student is less apt to wander astray from the facts of the case.
