(Q) Anger causes poisons to be secreted from the glands. Joy has the opposite effect. The adrenal glands are principally involved, reacting through the solar plexus to all parts of the body.
(A) The adrenals principally, but ALL of the glands are involved; as: A nursing mother would find that anger would affect the mammary glands. One pregnant would find the digestive glands affected. The liver, the kidneys and ALL glands are affected; though it is correct that the reaction is PRINCIPALLY through the adrenals. [Cayce, 281-54]
"Ye have gained that the first movement of same physically reaches out and becomes the brain, through which the pineal in its activity brings its physical development; and that it is related to the mind of the body and the environs of the body supplying physical activities to that developing physical entity. Ye know that it reverts then to the brain of the nervous system, to the solar plexus center, and then reflexes through its own MENTAL activity to the physical forces of the still developing body. Ye know that when such a body has developed, when gestation has been completed and it becomes an entity in itself, - because of its center through which all physical and mental impulse has passed, - it is then cut asunder - and yet functions on. Why? How?" [Cayce, 281-57]
