The first question:
What is turning inwards?
Turning inwards is not a turning at all. Going inwards is not a going at all. Turning inwards simply means: that you have been running after this desire and that, and you have been running and running and you have been coming again and again to frustration; that each desire brings misery, that there is no fulfillment through desire; that you never reach anywhere, that contentment is impossible. Seeing this truth, that running after desires takes you nowhere, you stop. Not that you make any effort to stop; if you make any effort to stop it is again running, in a subtle way. You are still desiring – maybe now it is desirelessness that you desire.
If you are making an effort to go in, you are still going out. Any effort can only take you out, outwards. All journeys are outward journeys, there is no inward journey. How can you journey inwards? – you are already there, there is no point in going. When going stops, journeying disappears, when desiring is no more clouding your mind, you are in. This is called turning in. But it is not a turning at all, it is simply not going out.
But in language it is always a problem to express these things.
There is an ancient parable: It was a beautiful afternoon and a tortoise went for a walk on the land. He rested under sunlit trees and he roamed around in the bushes just for the delight of it. Then he came back to the pond. One of his friends, a fish, asked, “Where have you been?” and he said “I went for a walk on the land.” The fish said, “What do you mean by ‘a walk on the land’? You must mean swimming.” And the tortoise laughed and he said, “No, it was not swimming, it was nothing like swimming. It was a walk on the solid land.” And the fish said, “Are you kidding or something? I have been to every place, you can swim everywhere. I have never seen a place where you cannot dive and swim. You are talking nonsense. Have you gone mad?”
You understand the difficulty of the fish? She has never been on land, walking on land makes no sense. If the tortoise wants to make sense of his statement he will have to say, “I went swimming on the solid land.” Which will be absurd. But only the word “swimming” can be understood by the fish.
