Practice this until the vibration wave begins instantly upon mental command, and moves steadily until fade-out. By this time, you will have noticed the "roughness" of the vibrations at times, as if your body is being severely shaken right down to the molecular or atomic level. This may be somewhat uncomfortable, and you will feel a desire to "smooth" them out. This is accomplished by "pulsing" them mentally to increase their frequency. Their original vibratory rate seems to be on the order of some twenty-seven cycles per second (this is the rate of the vibration itself, not the head-to-toe frequency). The pattern responds to this pulsing command very subtly and slowly at first. Your first indication of success is when the vibrations no longer seem rough and shaking. You are well on your way to control when they produce a steady, solid effect. It is essential that you learn and apply this speed-up process. The faster vibration effect is the form that permits disassociation from the physical. Once you have set the momentum of the speed-up, the acceleration seems to take place automatically. Eventually, you may sense the vibrations only as they begin. They will increase their frequency—like a motor starting up—until the frequency is so high that you are unable to perceive it. At this phase, the sensory effect is one of body warmth, slightly tingling, but not excessively so. Consistent achievement of this stage is the sign that you are ready for the first physical disassociation experiments. Another word of warning is in order here. Beyond this point, I believe you cannot turn back. Ultimately, you will be committed to the reality of this other existence. How this will affect your personality, your daily life, your future, and your philosophies rests entirely with you as an individual. For once you have been "opened" to this other reality, you cannot completely shut it out again, try as you might. The pressure of material affairs may sublimate it for a time, but it will return. You cannot always stay on guard against its reopening. As you start to sleep or awaken, when you merely relax, the vibrational surge may come without call. You can shut it off, of course, but eventually you become too tired to bother— and you are off on another excursion. You sense that you are fighting against yourself. And who wants to fight one's self—at the price of a good night's sleep!
