(2) For the purpose of convenience of thought and study, the Hermetic Philosophy considers that the Universe may be divided into three great classes of phenomena, known as the Three Great Planes, namely: 1. The Great Physical Plane. 2. The Great Mental Plane. 3. The Great Spiritual Plane.

(7) You will kindly remember, however, that the Three Great Planes are not actual divisions of the phenomena of the Universe, but merely arbitrary terms used by the Hermetists in order to aid in the thought and study of the various degrees and Forms of universal activity and life. The atom of matter, the unit of force, the mind of man, and the being of the arch -angel are all but degrees in one scale, and all fundamentally the same, the difference between solely a matter of degree, and rate of vibration--all are creations of THE ALL, and have their existence solely within the Infinite Mind of THE ALL.

(1) In the Secret Doctrine of the Rosicrucians, we find the following Sixth Aphorism: The Sixth Aphorism VI. As Life is the Essence of Spirit, so is Consciousness the Essence of Life. Spirit is One, yet it manifests in many forms of Life. Life is One, yet it manifests in many forms of Consciousness. While the forms of manifested Consciousness are innumerable, yet the wise know Consciousness to manifest on Seven Planes: and these Planes of Consciousness are known to the wise as (1) The Plane of the Elements; (2) The Plane of the Minerals; (3) The Plane of the Plants; (4) The Plane of the Animals; (5) The Plane of the Human; (6) The Plane of the Demi-Gods; (7) The Plane of the Gods .

(15) The Plane of Elemental Mind (A) comprises the state or condition, and degree of mental and vital development of a class of entities unknown to the average man, but recognized to occultists. They are invisible to the ordinary senses of man, but, nevertheless, exist and play their part of the Drama of the Universe. Their degree of intelligence is between that of the mineral and chemical entities on the one hand, and of the entities of the plant kingdom on the other. There are seven subdivisions to this plane, also.

(8) The Hermetists sub-divide each of the Three Great Planes into Seven Minor Planes, and each of these latter are also sub-divided into seven sub-planes, all divisions being more or less arbitrary, shading into each other, and adopted merely for convenience of scientific study and thought.

(9) The Great Physical Plane, and its Seven Minor Planes, is that division of the phenomena of the Universe which includes all that relates to physics, or material things, forces, and manifestations. It includes all forms of that which we call Matter, and all forms of that which we call Energy or Force. But you must remember that the Hermetic Philosophy does not recognize Matter as a thing in itself, or as having a separate existence even in the Mind of THE ALL. The Teachings are that Matter is but a form of Energy--.that is, Energy at a low rate of vibrations of a certain kind. And accordingly the Hermetists classify Matter under the head of Energy, and give to it three of the Seven Minor Planes of the Great Physical Plane.

(17) The Plane of Elemental Mind (B), in its seven sub-divisions, comprises the states and conditions of a higher form of "elemental" or unseen entities, playing their part in the general work of the Universe, the mind and life of which form a part of the scale between the Plane of Plant Mind and the Plane of Animal Mind, the entities partaking of the nature of both.

(1) We have now reached that stage of our presentation of the subject of the Secret Doctrine of the Rosicrucians, and particularly of that phase known as the Seven Planes of Consciousness, in which we ask the student to consider those phases of Consciousness above the Plane of Animal Consciousness. Accordingly our present consideration is with those three great Planes of Consciousness which begin with the Plane of Human Consciousness, and include the Planes of the Consciousness of the Demi-Gods, and which find their highest manifestation on the Plane of the Consciousness of the Gods.

(7) I. The Plane of the Elements On this Plane of Consciousness is manifested the actions and reactions between the subtle elements of which all material forms are composed. Here occurs the play between the atoms, the electrons, the ions, the corpuscles, and the still more tenuous particles of substance of which science has as yet no knowledge. And, going still further back, it may be said that on this plane occurs the play of phases of substance as much more tenuous and subtle than the electrons as the latter are more tenuous than the atoms. Little can be said concerning these practically unknown forms and phases of matter, although the occult teachings are quite full of them.

(11) The Plane of Matter (A) comprises the forms of Matter in its form of solids, liquids, and gases, as generally recognized by the text-books on physics. The Plane of Matter (B) comprises certain higher and more subtle forms of Matter of the existence of which modern science is but now recognizing, the phenomena of Radiant Matter, in its phases of radium, etc., belonging to the lower sub-division of this Minor Plane. The Plane of Matter (C) comprises forms of the most subtle and tenuous Matter, the existence of which is not suspected by ordinary scientists. The Plane of Ethereal Substance comprises that which science speaks of as "The Ether", a substance of extreme tenuity and elasticity, pervading all Universal Space, and acting as a medium for the transmission of waves of energy, such as light, heat, electricity, etc. This Ethereal Substance forms a connecting link between Matter (so-called) and Energy, and partakes of the nature of each. The Hermetic Teachings, however, instruct that this plane has seven sub-divisions (as have all of the Minor Planes), and that in fact there are seven ethers, instead of but one.

(3) These divisions are more or less artificial and arbitrary, for the truth is that all of the three divisions are but ascending degrees of the great scale of Life, the lowest point of which is undifferentiated Matter, and the highest point that of Spirit. And, moreover, the different Planes shade into each other, so that no hard and fast division may be made between the higher phenomena of the Physical and the lower of the Mental; or between the higher of the Mental and the lower of the Physical.

(11) The Plane of Elemental Consciousness, like all the great Planes of Consciousness, contains seven sub-planes, and each of these seven minor planes, and so on until the multiplication has been made seven times. The sub-plane we have just briefly considered is but one of the seven, and the remaining six are equally important. In these unmentioned subplanes there are manifestations utterly unknown to modern science and to the uninformed person, but of which the occult masters have made a careful and thorough study.

(5) At the beginning we may as well consider the question so often asked by the neophyte, who desires to be informed regarding the meaning of the word "Plane", which term has been very freely used, and very poorly explained, in many recent works upon the subject of occultism. The question is generally about as follows: "Is a Plane a place having dimensions, or is it merely a condition or state?" We answer: "No, not a place, nor ordinary dimension of space; and yet more than a state or condition. It may be considered as a state or condition, and yet the state or condition is a degree of dimension, in a scale subject to measurement." Somewhat paradoxical, is it not? But let us examine the matter. A "dimension," you know, is "a measure in a straight line, relating to measure," etc. The ordinary dimensions of space are length, breadth, and height, or perhaps length, breadth, height, thickness or circumference. But there is another dimension of "created things" or "measure in a straight line," known to occultists, and to scientists as well, although the latter have not as yet applied the term "dimension" to it--and this new dimension, which, by the way, is the much speculated -about "Fourth Dimension," is the standard used in determining the degrees or "planes."

(24) On the Seven Minor Planes of the Great Spiritual Plane exist Beings of whom we may speak as Angels; Archangels; Demi-Gods. On the lower Minor Planes dwell those great souls whom we call Masters and Adepts. Above them come the Great Hierarchies of the Angelic Hosts, unthinkable to man; and above those come those who may without irreverence be called "The Gods," so high in the scale of Being are they, their being, intelligence and power being akin to those attributed by the races of men to their conceptions of Deity. These Beings are beyond even the highest flights of the human imagination, the word "Divine" being the only one applicable to them. Many of these Beings, as well as the Angelic Host, take the greatest interest in the affairs of the Universe and play an important part in its affairs. These Unseen Divinities and Angelic Helpers extend their influence freely and powerfully, in the process of Evolution, and Cosmic Progress. Their occasional intervention and assistance in human affairs have led to the many legends, beliefs, religions and traditions of the race, past and present. They have superimposed their knowledge and power upon the world, again and again, all under the Law of THE ALL, of course.

(19) The Plane of Elemental Mind (C), in its seven sub-divisions, comprises those entities or beings, invisible as are all such elemental forms, which partake of the nature of both animal and human life in a degree and in certain combinations. The highest forms are semi-human in intelligence.

(4) The reason that the Rosicrucians place these three higher planes of consciousness in a trinity of circles, apparently apart from the lower four planes, is that on these three higher planes of consciousness the individual soul manifests Self-Consciousness, or the consciousness of "I Am," in at least a certain degree; while on the lower four planes this consciousness of "I" is entirely absent, and the mental activity is more or less automatic and instinctive. This distinction will be brought out as we proceed.

(3) The Symbol is interpreted as follows: (1) The Infinite Unmanifest manifests itself in the Elemental Soul; (2) the Elemental Soul takes upon itself the outward form of Mineral Substance; (3) The Mineral Soul evolves from itself the Plant Soul; (4) the Plant Soul evolves from itself the Animal Soul; (5) the Animal Soul evolves from itself the Human Soul; (6) the Human Soul unfolds into the Soul of the Demi-Gods; (7) the Soul of the Demi-Gods unfolds into the Soul of the Gods; and finally, the Soul of the Gods once more is resolved into Pure Spirit, which is represented by the blank space at the centre of the symbol. This statement will be more clearly apprehended by those who have carefully studied the preceding chapters conveying instruction concerning the Seven Planes of Consciousness, and much of the information contained in those chapters is to be taken into consideration in the study of the present chapter.

(7) There are many planes of Being--many sub-planes of Life--many degrees of existence in the Universe. And all depend upon the advancement of beings in the scale, of which scale the lowest point is the grossest matter, the highest being separated only by the thinnest division from the SPIRIT of THE ALL. And, upward and onward along this Scale of Life, everything is moving. All are on the Path, whose end is THE ALL. All progress is a Returning Home. All is Upward and Onward, in spite of all seemingly contradictory appearances. Such is the message of the Illumined.
