Spending time in the forest cleanses the mind. The sound of leaves rustling in the wind, the sound of the wind blowing through the reeds, the sound of frogs croaking in the ponds: All you can hear are the sounds of nature; no extraneous thoughts enter the mind. If you empty your mind and receive nature into your entire being, there is no separation between you and nature. Nature comes into you, and you become completely one with nature. In the moment that the boundary between you and nature disappears, you feel a profound sense of joy. Then nature becomes you, and you become nature.

       I have always treasured such experiences in my life. Even now, I close my eyes and enter a state in which I am one with nature. Some refer to this as anatman, or “not-self,” but to me it is more than that, because nature enters and settles into the place that has been made empty. While in that state, I listen to the sounds that nature hands to me—the sounds of the pine trees, the sounds of the bugs—and we become friends. I could go to a village and know, without meeting anyone, the disposition of the minds of the people living there. I would go into the meadow of the village and spend the night there, then listen to what the crops in the fields would tell me. I could see whether the crops were sad or happy and that would tell me the kind of people who lived there.

      The reason I could be in jail in South Korea and the United States, and even North Korea, and not feel lonely and isolated is that even in jail I could hear the sound of the wind blowing and talk to the bugs that were there with me.
