If you meditate on open unclouded sky, suddenly you will feel that the mind is disappearing, the mind is dropping away. There will be gaps. Suddenly you will become aware that it is as if the clear sky has entered in you also. There will be intervals. For a time being, thoughts will cease – as if the traffic has ceased and there is no one moving. In the beginning it will be only for moments, but even those moments are transforming. By and by the mind will slow down, bigger gaps will appear. For minutes together there will be no thought, no cloud.
To meditate on the sky is beautiful. Just lie down so you forget the earth; just lie down on your back on any lonely beach, on any ground, and just look at the sky. But a clear sky will be helpful – unclouded, endless. And just looking, staring at the sky, feel the clarity of it – the uncloudedness, the boundless expanse – and then enter that clarity, become one with it. Feel as if you have become the sky, the space.
But if it is not summer what will you do? If the sky is clouded, not clear, then close your eyes and just enter the inner sky. Just close your eyes, and if you see some thoughts, just see them as if they are floating clouds in the sky. Be aware of the background, the sky, and be indifferent to thoughts.
We are too much concerned with thoughts and never aware of the gaps. One thought passes, and before another enters there is a gap – in that gap the sky is there. Then, whenever there is no thought, what is there? The emptiness is there. So if the sky is clouded – it is not summertime and the sky is not clear – close your eyes, focus your mind on the background, the inner sky in which thoughts come and go. Don't pay much attention to thoughts; pay attention to the space in which they move. Then the summer sky happens within.
