Anger starts as an impulsive reaction to some aggressive situation in the form of a wave-radiation from consciousness. It reaches the brain and activates the pituitary through hypothalamus. Pituitary hormone (ACTH) reaches and reacts with the adrenal gland and stimulates it to release adrenaline in the blood stream, which reaches the motor area in the brain via the neurotransmitters. Finally, it manifests itself by producing certain physiological conditions making the body ready for aggression. Thus science is aware of the centre of generation of impulses and the paths of their transmission to the brain.
If the transmission line is surgically destroyed, the instinct cannot generate feeling and is incapable of commanding action. By stimulating or inhibiting certain portions of the brain, particularly hypothalamus, anger, fear, sexual excitement and other urges can be neutralized. The field that manifests them remains passive because the transmission is cut off. It must, however, be remembered that in such an operation, only the transmission of the impulsive agitation is cut off but the generation is not stopped and continues. The manifestation in the final field does not occur but the primary centre of agitation remains active This means that by blocking the transmission, a temporary transformation of the behaviour is achieved, but the origin of the agitation remains as active as before. In other words, a mask is used to hide the hideousness of the face while the face continues to remain as hideous as before. The change is external and superfluous, not internal.
Thus, the surgical treatment of controlling the impulsive forces can be looked upon as an expedient and not a permanent solution of the problem. The permanent remedy is to achieve a state of blissful tranquillity in which the impelling force of the urge fails to generate the wave. Frequent repetitions strengthen the agitational force of impulsive drive such as anger, fear etc. Anger, for example, grows if it is fed with anger. If no nourishment is fed to anger, it will wither and die down. Psychic science (adhyatma) is based on the doctrine of equanimity and its technique is self-awareness. Self-awareness is the foundation of tranquil (waveless) consciousness. When one reached this state, there is neither like nor dislike, neither attachment nor aversion. In this state of consciousness, the wave of anger is not suppressed, but the force which generates the wave of anger is eradicated. Whereas the surgical implements or medicinal remedies strike at the brain, spinal cord or nerves i.e. the instruments of transmission, the self-awareness and tranquillity released by meditation strike not only on the transmission system but the prime mover that drives the generator of impulses. It is a process of extermination from the roots and that is why the solution is permanent and everlasting. The technique of realising the tranquil (waveless) state is the perception of psychic centres. Thus the perception of psychic centres is not merely an important means of self-realisation, but it is the only means.
