Thirdly, eyes are very liquid, moving, in constant movement, and that movement has its own rhythm, its own system, its own mechanism. Your eyes are not moving at random, anarchically. They have a rhythm of their own and that rhythm shows many things. If you have a sexual thought in the mind, your eyes move differently – with a different rhythm. Just by looking at your eyes and the movement, one can say what type of thought is moving inside. When you feel hungry and a thought of food is inside, eyes have a different movement.
So now even your dreams can be penetrated. Your eye movements can be recorded while you are asleep. And remember, even in dreams your eyes behave similarly. If you are seeing a naked woman in your dream, this can be judged from your eye movements. Now they are mechanical devices to record what are the movements of the eyes.
These eye movements are called REM – Rapid Eye Movements. They can be recorded on a graph, just like an electrocardiogram. If you have been sleeping for the whole night, your eye movements can be continuously recorded. And then the graph can show when you were dreaming and when you were not, because when you are not dreaming the eyes stop and become static. When you are dreaming they move, and the movement is like when you are seeing something on the screen. If you are seeing a film, the eyes have to move. In the same way, in your dream your eyes move: they are seeing something. They follow the movements of the film. For your eyes there is no difference between an actual film being shown on the screen or just a dream film.
So these REM recorders tell how much you dreamt in the night and for how many moments you were not dreaming, because the eyes stop their movement when you are not dreaming. There are many persons who say they never dream. They just have a very absent-minded memory – nothing else. They cannot remember, that is the only thing. They are actually dreaming, for the whole night they are dreaming, but they cannot remember. Their memory is not good, that is all. So in the morning when they say there was no dream, do not believe them.
Why do the eyes move when there is a dream, and why do the eyes stop when there is no dream? Each eye movement is joined to the thought process. If thinking is there, the eyes will move. If there is no thinking, the eyes will not move – there is no need.
So remember this third point also, that eye movements and thinking are joined together. That is why if you stop your eyes and their movements, your thought process will stop immediately. Or if your thought process stops your eyes will stop automatically.
And one point more, the fourth. The eyes move continuously from one object to another. From A to B, from B to C, they go on moving. Movement is their nature. It is just like a river flowing: movement is their nature! And because of that movement, they are so alive! Movement is also life.
