1. That congestion which produces its effect within the center itself, and therefore and consequently, upon the gland. It is inhibited, either as it pours into the center (when it does not affect the gland except in a negative sense), or as it leaves it (when its effect will be positive in some way or another). When the difficulty takes place as it pours into the center, then the energy is thrown back upon its originating source - either the astral or mental bodies - and you have a psychological inhibition. There is no impetus from within to which the allied gland can respond. When the difficulty is in the outlet into the physical body, you will have no free flow of force, the gland related to the center will be definitely affected, and either be over-stimulated by the non-rhythmic flow or undernourished. This in turn affects the glandular secretion and later the blood stream. [308]
2. That congestion which takes place as the energy or the life force flows throughout the physical body, and as it flows finds there certain forms of weakness, various diseased areas and regions where its flow is impeded or too rapidly circulated. The flow of energy can be arrested in certain areas and can nourish also diseased areas in the body, or can also cure and cleanse them. A temporary congestion can be of beneficent value as well as a malefic force. This may surprise you?

Again, I have to repeat how vast is the subject with which we are dealing, and all these earlier instructions and the answers which I give to the questions only serve to show how abstruse the matter is. But if you will have patience and will be willing to learn by absorption more than by analysis, you will later discover that you know much - intuitively and discriminately.
