Look into the blue sky and go on looking.
Do not think about it; do not say it is beautiful. Do not say, 'How lovely!' Do not appreciate the color; do not start thinking. If you start thinking, you have stopped. Now your eyes are not moving into the blue, the infinite blue. Just move, just look – do not think. Do not create words; they will become barriers. Not even 'blue sky' should be said. Do not verbalize.
There should be just a pure, innocent look into the blue sky. It never ends. You will go on and on and on and on, and suddenly, because there is no object, just a vacuum, suddenly you will become aware of yourself. Why? Because if there is any vacuum your senses become useless. Senses are only useful if there is an object.
If you are looking at a flower, then you are looking at something – the flower is there. The sky is not there. What do we mean by a sky? That which is not there. Sky means the space. All objects are in the sky, but the sky is not an object. It is just the vacuum, the space in which objects can exist. The sky itself is just pure emptiness. Look into it.
What will happen? In emptiness, there is no object to be grasped by the senses. Because there is no object to be grasped, clung to, senses become futile. And if you are looking into the blue sky without thinking, without thinking, suddenly you will feel that everything has disappeared; there is nothing. In that disappearance you will become aware of yourself. Looking into this emptiness, you will become empty.
If you are looking into the emptiness, there is nothing to be reflected – or only the blue infinite sky. If it is reflected, if you feel the blue infinite sky within, you will become serene, you will find serenity.
In emptiness, how can the mind function? It stops; it disappears. In the disappearance of the mind – the mind that is tense, worried, filled with thoughts that are relevant, irrelevant – in that disappearance of the mind, serenity.
