The process of assimilation is carried on in this triangle, and the prana which enters into either center, circulates three times around the triangle before being transmitted to all parts of the etheric vehicle and from thence to the dense physical body. The main organ of assimilation is the spleen - the etheric center and the dense physical organ. The vital essence from the sun is passed into the etheric spleen, and is there subjected to a process of intensification or devitalization, according to the condition, healthy or not, of that organ. If the man is in a healthy state the emanation received will be augmented by his own individual vibration, and its rate of vibration will be keyed up before it is passed on into the physical spleen; or it will be slowed down and lowered if the man is in a poor condition of health.

These three centers are in the form that all centers take, of saucer-like depressions, resembling somewhat the appearance of small whirlpools, and which draw within their sphere of influence the currents that come their way.

Here again can be seen the correspondence to the escape of all essences from within any ring-pass-not when the cycle has been completed.

This matter of the etheric body is of a very practical interest, and when its importance is better realized, men will attend to the distribution of prana within the body with closer attention, and will see that the vitalization of the body, via the three centers, proceeds unhindered.

The subject has necessarily to be handled in a superficial manner, and only outlines and scattered hints can be given. Nevertheless, it will be found that if this teaching is studied with care, it will convey a knowledge of truths whose caliber and content will prove invaluable and of a kind hitherto not given out. The place of the etheric sheath as a separator or ring-pass-not, and its functions as a receiver and distributor of prana, are dealt with here in a larger sense than heretofore, and the subject may later be enlarged.
