The Plane of Human Mind, in its seven sub-divisions, comprises those manifestations of life and mentality which are common to Man, in his various grades, degrees, and divisions.  In this connection, we wish to point out the fact that the average man of today occupies but the fourth sub-division of the Plane of Human Mind, and only the most intelligent have crossed the borders of the Fifth Sub-Division.  It has taken the race millions of years to reach this stage, and it will take many more years for the race to move on to the sixth and seventh sub-divisions, and beyond.  But, remember, that there have been races before us which have passed through these degrees, and then on to higher planes.  Our own race is the fifth (with stragglers from the fourth) which has set foot upon The Path.  And, then there are a few advanced souls of our own race who have outstripped the masses, and who have passed on to the sixth and seventh sub-division, and some few being still further on.  The man of the Sixth Sub-Division will be “The Super-Man”; he of the Seventh will be “The Over-Man.”

In our consideration of the Seven Minor Mental Planes, we have merely referred to the Three Elementary Planes in a general way.  We do not wish to go into this subject in detail in this work, for it does not belong to this part of the general philosophy and teachings.  But we may say this much, in order to give you a little clearer idea, of the relations of these planes to the more familiar ones—­the Elementary Planes bear the same relation to the Planes of Mineral, Plant, Animal and Human Mentality and Life, that the black keys on the piano do to the white keys.  The white keys are sufficient to produce music, but there are certain scales, melodies, and harmonies, in which the black keys play their part, and in which their presence is necessary.  They are also necessary as “connecting links” of soul-condition; entity states, etc., between the several other planes, certain forms of development being attained therein—­this last fact giving to the reader who can “read between the lines” a new light upon the processes of Evolution, and a new key to the secret door of the “leaps of life” between kingdom and kingdom.  The great kingdoms of Elementals are fully recognized by all occultists, and the esoteric writings are full of mention of them.  The readers of Bulwer’s “Sanoni” and similar tales will recognize the entities inhabiting these planes of life.

Passing on from the Great Mental Plane to the Great Spiritual Plane, what shall we say?  How can we explain these higher states of Being, Life and Mind, to minds as yet unable to grasp and understand the higher subdivisions of the Plane of Human Mind?  The task is impossible.  We can speak only in the most general terms.  How may Light be described to a man born blind—­how sugar, to a man who has never tasted anything sweet—­how harmony, to one born deaf?
