L.S.D. is much discussed today. It is improbable to think that the present-day citizen, the one who studies in the university will not know its name and use. In some university campuses, sadhana kendras or institutions where meditation and yoga are being taught, L.S.D. is also being used extensively. This is because after using it just once, man begins to have hallucinations and go through varied kinds of experiences. He thinks he has actually been transported to heaven and other such new worlds. Then he begins to think L.S.D. is a gift of god. L.S.D. contains serotonin. Our brain too has serotonin. It affects our brain in great measure. It distorts our very outlook. It becomes a false outlook. Serotonin influences the entire conduct, which becomes full of distortions.
The effort of meditation is to change these secretions. When we contemplate on the center of peace (shaktikendra), the center of enlightenment (jyotikendra) and the center of intuition (darshankendra), our hypothalamus is influenced. This in turn influences the pineal and the pituitary glands. When these psychic centers are influenced, the secretions change.
In the method of Preksha Dhyan, the meditation on the psychic centers is very significant. It is significant because without this a man cannot be transformed. We may meditate on the breath or on the body or even on colours, but the truth is that unless we get to the root of it, that is, unless the psychic centers are influenced, the secretions cannot be changed and a man's behavioural pattern cannot be altered, his habits cannot be altered and his nature cannot be altered. Without energizing the psychic centers, the conscious mind cannot be awakened, numbness cannot be avoided and perspectives cannot be changed.
We can say that till then the perspective does not have right base.
