Be aware of the gap between waking and sleep
There are some turning points in your consciousness. At these turning points you are nearer to your center than at other times. In the morning, when sleep is going, vanishing, and you are feeling awake but not yet awake, just at the midpoint, you are in a neutral gear. There is a point when you are not asleep and not awake, just in the middle. From sleep to waking, your consciousness changes the whole mechanism. It jumps from one mechanism to another. Between the two mechanisms, there is no mechanism; there is a gap. Through that gap you can have a glimpse of your being.
The same happens in the night when you are again jumping from your waking mechanism to your sleeping mechanism, from your consciousness to the unconscious. Between the two if you can be awake, between the two if you can become aware, between the two if you can remember yourself, you will have a glimpse of your real being.
While going to sleep, relax. Close your eyes, make the room dark. Just close your eyes and start waiting. The sleep is coming; just wait, don’t do anything, just wait! Your body is relaxing, the body is becoming heavy: feel it. Have the feeling of it. Sleep has its own mechanism, it starts working. Your waking consciousness is vanishing. Remember, because the moment will be very subtle and the moment will be atomic. If you miss, you miss. It is not a very long period – a single moment, a very small gap, and you will change from waking to sleep. Just wait, fully aware, someday, suddenly it happens, you become aware that you are neither awake nor asleep. Anything which is so new, unknown previously, is bound to give a certain fear. when you will have experienced it again and again, will give you another feeling also: that you are neither alive nor dead, neither this nor that. This is an abyss. There is no end to it. Once you know it, you also have become endless. Then you know who you are, what is your real being, what is your authentic existence.
Be aware of the gap, be awake while passing from one state to another have a glimpse. And once you know when the gap comes, you become the master of it. You have the key; you can open that gap anytime and enter into it. A different dimension of being, the real dimension, opens.
