The practice part of it is that it doesn’t matter if you think you lost the coin and start to be unhappy about life. That is another theory. And it doesn’t matter how many times that theory rises. Even that theory is the coin. A koan practice means that you go back to the river over and over again and you can trust that process.
“A koan is a little healing story, a conversation, an image, a fragment of a song. It’s something to keep you company, whatever you are doing. There’s a tradition of koan study to transform your heart and the way you move in the world.” March 2016.
