That care must be taken to interpret all here given in terms of spirit and not of matter or form. This realisation will save the student from much later confusion. That we are considering facts which are substantial and real on the mental plane-the plane on which all the major initiations take place-but which are not materialised on the physical plane, and are not physical plane phenomena. The link between the two planes exists in the continuity of consciousness which the initiate will have developed, and which will enable him to bring through to the physical brain, occurrences and happenings upon the subjective planes of life. Corroboration of these occurrences, and proof of the accuracy of the transmitted knowledge will demonstrate as follows:-
In and through the etheric centres. These centres will be greatly stimulated, and will, through their increased inherent energy, enable the initiate to accomplish more in the path of service than he ever before dreamed possible. His dreams and ideals become, not possibilities, but demonstrating facts in manifestation.
The physical centres, such as the pineal gland and the pituitary body, will begin to develop rapidly, and he will become conscious of the awakening of the "Siddhis" or powers of the soul, in the higher connotation of the words. He will be aware of the process of conscious control, and of self-initiated manipulations of the above powers. He will realise the methods of egoic contact and the right direction of force.
The nervous system, through which the emotional body or astral nature works, will become highly sensitised, yet strong withal. The brain will become ever more rapidly an acute transmitter of the inner impulses. This fact is of real importance, and will bring about-as its significance becomes more apparent- a revolution in the attitude of educators, of physicians and others, to the development of the nervous system and the healing of nervous disorders.
Occult memory. The initiate finally becomes aware increasingly of the growth of that inner recollection, or "occult memory," which concerns the work of the Hierarchy and primarily his share in the general plan. When the initiate, who occultly recalls, in his waking consciousness, a ceremonial fact, finds all these manifestations of increased growth and conscious realisation in himself, then the truth of his inner assurance is proven and substantiated to him.
It must be remembered that this inner substantiation is of no value to anyone but the initiate. He has to prove himself to the outer world through his life of service and the work accomplished, and thereby call forth from all his environing associates a recognition that will show itself in sanctified emulation and a strenuous effort to tread the same path, actuated ever by the same motive,- that of service and brotherhood, not self-aggrandisement and selfish acquirement.
