This dynamic first ray energy is usually employed by the trained spiritual healer when it is apparent to him that the patient's hour has come and release approaches. In cases where the first ray is the soul ray of either healer or patient, this application of first ray energy must move from head center to head center, and from thence to the area of distress and to the center allied with the location. This may cause (when healing is possible and karmically correct) a temporary increase of the trouble; this is owing to the fact that the incoming energy "expels dynamically" the very seed or roots of the disease. There may be a rise in temperature, or a collapse of some kind or another, and for this the healer, the patient and the attendant physician must be prepared and should take the needed physical steps for amelioration - steps as ordained by the orthodox medical profession, which will offset the purely physical reaction. Where the soul ray of the patient is not on the first ray, but the first ray is the ray of the personality, the healer must use great caution in applying first ray energy, and should proceed very slowly and gradually through the center on the line of 1-3-5-7 which is nearest to the seat of trouble, passing the energy through that center and thence to the center (whichever that may be) found in the locality of the disease. If that particular center happens to be on the line of 3-5-7, the healer will have to exercise special care, or else the dynamic first ray energy will destroy and not heal.
