Also, meditate on knowledge that comes during sleep.
Also, meditate on anything that appeals to you.
Thus, the yogi becomes master of all, from the infinitesimal to the infinite.
Man sleeps almost one-third of his life, twenty years approximately. But sleep has been neglected, terribly neglected. Nobody thinks about it, nobody meditates on it. This has happened because man has paid too much attention to the conscious mind.
Mind has three dimensions. Just as matter has three dimensions, mind also has three dimensions. Only one dimension is conscious, another dimension is unconscious, and there is still another dimension which is superconscious. These three dimensions are of the mind – just like matter, because deep down mind is also matter. Or, you can say it otherwise, that matter is also mind. It has to be so, because only one exists.
Mind is subtle matter; matter is gross mind. But ordinarily man lives only in one dimension, the conscious. Sleep belongs to the unconscious; dreaming belongs to the unconscious. Meditation, ecstasy, belong to the superconscious, just like waking and thinking belong to the conscious. So, we have to go slowly into this phenomenon of mind.
The first thing about mind to be remembered is, it is just like an iceberg – the topmost part is on the surface. You can see it, but it is only one-tenth of the whole; nine-tenths is hidden underneath. You cannot see it ordinarily, unless you move into the depths. But these are only two dimensions. There is a third dimension: as if a part of the iceberg has evaporated and has become a small cloud and hovers in the sky. It is difficult to reach to the unconscious; it is almost impossible to reach to that cloud – of course part of the same iceberg, but evaporated.
That’s why meditation is so difficult, samadhi is so arduous. It takes one’s total energy, it demands one’s total devotion, only then the vertical movement into the cloudlike phenomenon of the superconscious becomes possible. The conscious is there; you are listening to me from the conscious. If you are thinking about what I am saying, if you are making a sort of dialogue inside with whatsoever I am saying – a sort of commentary goes on inside – this is the conscious mind.
But you can listen to me without thinking – in deep love, heart to heart, not in any way verbalizing what I am saying, judging what I am saying, right or wrong, no. No evaluation; you simply listen in deep love, as if the mind is paused and the heart listens and beats with joy. Then the unconscious is listening. Then whatsoever I say will go very deep, to your roots.
