So when I say conscious and unconscious, I don’t mean any fixed boundaries. There are none, there are no fixed boundaries. It is a fluctuating phenomenon. It depends on you to be less conscious or more conscious. You can create consciousness; you can train and discipline yourself for more consciousness or for less consciousness. If you train yourself for less consciousness, you will never be able to encounter the unconscious. Really, you will even become incapable of encountering the conscious.
When someone has taken some intoxicant, he is training his mind to be totally unconscious. When you go into sleep, or if you can be hypnotized, or if you can auto-hypnotize yourself, then you lose consciousness. There are many tricks, and many of those tricks which help you to be more unconscious are even known as religious practices. If you do any monotonous, repetitive thing – for example, if you go on continuously saying “Rama-Rama-Rama-Rama” in a very monotonous tone, you will become less conscious. And this constant repetition of “Rama-Rama-Rama” in a monotonous tone will be just auto-hypnotic. You will go to sleep: it is good for sleep.
If you can create monotony then you will be less conscious, because a bored mind cannot remain conscious. The boredom is too much, and the mind would like to go to sleep.
We know, every mother knows, how to put a child to sleep. A lullaby does nothing but create boredom. Every mother knows how to put a child to sleep. With a lullaby – a constant repetition of certain words – the child is bored, so he goes into sleep. This lullaby can be created by movement, by anything which is monotonous – by anything. Just move the child monotonously, rotate the child monotonously, and he will go to sleep because he feels bored. Even if you put the child’s head near your heart he will go to sleep, because your heartbeat is a very boring thing. So put the child near your heart, and he will feel bored because of the constant repetition of the heartbeat. The child knows it very well because he has heard it continuously for nine months. Even old persons can use the tick-tick of a clock for going into sleep, and the reason is only the resemblance to the heartbeat. So if you feel that sleep is not coming, just concentrate on your clock and feel the beat, and soon you will drop into sleep.
You can create unconsciousness by creating boredom. By taking any intoxicant, by taking any drug, any sedative, any tranquilizer, you can create unconsciousness. Consciousness can also be created, but then quite different methods have to be used.
