hallucinate "mind pictures," or light patterns. These seem to have no great significance, and may merely be forms of neural discharge. I can remember, for example, attempting to achieve this state after watching a football game on TV for several hours. All I saw were mind pictures of football players tackling, running, passing, etc. It took at least a half hour for the pattern to fade away. These mind pictures are apparently related to your visual concentration in the preceding eight or ten hours. The more intense the concentration, the longer it seems to take to eliminate the impressions. You have accomplished Condition B when you are able to lie indefinitely after the impressions have faded away, with no nervousness, and seeing nothing but blackness. Condition C is a systematic deepening of consciousness while in the B state. This is approached by carefully letting go of your rigid hold on the borderland sleep edge and drifting deeper little by little during each exercise. You will learn to establish degrees, of this deepening of consciousness by "going down" to a given level and returning at will. You will recognize these degrees by the shutting down of various sensory mechanism inputs. The sense of touch apparently goes first. You seem to have no feeling in any part of your body. Smell and taste soon follow. The auditory signals are next, and the last to fade out is vision. (Sometimes the last two are reversed; I suspect that the reason for vision being last is that the exercise calls for the use of the visual network, even in blackness.) Condition D is the achievement of C when one is fully rested and refreshed, rather than tired and sleepy, at the beginning of the exercise. This is quite important, and not nearly as easy to achieve as it is to write about. To enter the relaxation state full of energy and wakefulness is great insurance for maintaining conscious control. The best approach to take in the early attempts at the Condition D exercise is to start it immediately after you wake up from a nap or a night's sleep. Start the exercise before you move around in bed physically, while your body is still relaxed from sleep and your mind is fully alert. do not take too many liquids before sleeping, and you would not have the immediate need to empty your bladder upon awakening. Induction by drugs. None of the relaxation-producing drugs that are readily available seem to help. Barbiturates force a loss of conscious control and only bring a confused state in deeper consciousness. The same is true, to a lesser degree, of tranquilizers. Relaxation is obtained, but at the cost of perception. Alcohol in any form brings similar effects. More exotic compounds such as the alkaloids and hallucinogens may be more productive, I have not had enough experience or contact with these to offer
