All that can be done here in dealing with this profound subject is to enumerate briefly some of the cosmic influences which definitely affect our earth, and produce results in the consciousness of men everywhere, and which, during the process of initiation, brin about certain specific phenomena. First and foremost is the energy or frce emanating from the sun Sirius. If it might be so expressed, the energy of though, or mind force, in its totality, reaches the solar system from a distant cosmic centre via Sirius. Sirius acts as a transmitter, or the focalising centre, whence emanate those influences which produce self-consciousness in man.
During initiation, by means of the Rod of initiation (acting energy is momentarily intensified, and applied to the centres of the initiate with terrific force; were it not that the Hierophant and the two sponsors of the initiate pass it primarily through their bodies, it would be more than he could stand. This increase of mind energy results in an expansion and an apprehension of the truth as it is, and is lasting in its effects. It is felt primarily in the throat centre, the great organ of creation through sound.
Another type of energy reaches man from the Pleiades, passing through the Venusian scheme to us, just as the Sirian energy passes through Saturian. It has a definite effect upon the causal body, and serves to stimulate the heart centre. A third type of energy is applied to the initiate, and affects his head centre. It emanates from that one of the seven stars of the Great Bear whose ensouling life holds the same relationship to our Planetary Logos as the Ego does to a human being. This energy, therefore, is seven-fold, and differs according to a man's ray or type.
It is not possible here to state the order of the application of these varying types of energy, nor to give the initiation during which the man contacts the different types. These facts involve the secrets of the mysteries, and no purpose is served by revealing them. Other types of force from certain of the planetary schemes, as well as from cosmic centres, are brought into play by the Initiator and transmitted through the medium of the Rod to the various centres in the initiate's three vehicles, the mental, the astral,and the etheric centres.
At the fourth initiation a specialised type of force from a centre which must remain nameless is applied to a man's causal body, and is one of the causes of its final disintegration. In thinking of this matter of the attainment of the sons of men, we must recognise that as mankind completes one unification after another, the "Heavenly Men" on intuitional levels and on spiritual levels are completed, and in their turn go to the formation of the centres in the great "Heavenly Men" of the solar system.
These seven Heavenly Men, in Whose bodies each human Monad and each diva finds his place, form the seven centres in the body of the Logos. He, in His turn, forms the Heart centre (for God is Love) of a still greate Entity. The consummation of all for this solar system will be when the Logos takes His fifth initiation. When all the sons of men attain the fifth initiation. When all the sons of men attain the fifth initiation, He achieves. This is a great mystery and incomprehensible to us.
