Even if you are thinking of God it is an impurity, because the cloud is moving. The cloud is very white, but the cloud is there and the purity of the space is not there. A cloudless sky is not there. A cloud may be a black cloud, a sexual thought moving in the mind, or the cloud may be a white cloud, beautiful, a prayer moving in the mind, but in both cases the pure mind is not there. It is impure, clouded. And if the mind is clouded you cannot move in the heart.
This has to be understood because with thoughts you cling to the head. Thoughts are the roots, and unless those roots are cut you cannot fall back to the heart.
The child remains in the heart only up to the moment that thoughts crystallize, that thoughts start floating in his mind. Then they take root; then through education, culture, cultivation, they become rooted; then by and by the consciousness moves from the heart to the head. The consciousness can remain in the head only if there are thoughts. This is basic. If there are no thoughts, consciousness immediately drops back to its original innocence in the heart.
Hence so much emphasis on meditation, so much emphasis on non-thinking, on thoughtless awareness, on choiceless awareness, or on Buddha’s “right mindfulness,” which is just mindfulness without any thought, just being aware. What happens then? A very great phenomenon happens because when the roots are cut, immediately consciousness drops back to the heart, to the original place where it had been. You become a child again.
Jesus said, “Only those who are like children will enter into the kingdom of my God.” He refers to those persons whose consciousness has come back to the heart. They have become innocent, childlike.
But the first basic requirement is to put mind-stuff in such inexpressible fineness….
Thoughts can be expressed. There is not a single thought which is inexpressible, nor can there be. If it is inexpressible you cannot think it; if you can think it, it is expressible. There is not a single thought which you can say is inexpressible. The moment you can think it, it has become expressible – you have already expressed it to yourself.
Consciousness, pure consciousness, is inexpressible. That is why mystics go on saying that they cannot express what they know. Logicians always raise the question that if you know, then why can’t you say it? And their argument has meaning and significance. If you really say that you know then why can’t you express it?
For a logician, knowledge must be expressible – that which can be known can be made known to others, there is no problem. If you have known it, then where is the problem? You can make it known to others. But the mystic’s knowledge is not of thoughts. He has not known it as a thought, he has known it as a feeling. So really, it is not good to say, “I know truth.” It is better to say, “I feel.” It is not good to say, “I have known truth.” It is better to say, “I have felt it.” That is a more accurate description of the phenomenon because the “knowledge” is through the heart it is like feeling, it is not like knowledge.
