One of the distinctive features of the collection “The Whole World Is One Flower” is its scope. Tae Son Sa Nim included not only koans of Chinese chan and Korean son, but also teachings of Laozi and the Christian tradition. Any religion is a language intended to express what lies beyond language. In the beginning there was the word, but before the beginning there wasn’t even a whisper. When Buddha lifted a flower, when Jesus took a child into his arms, they were saying the same thing. We can point to this by using the words of any religion. Thus, emptiness equals fullness, and the Kingdom of God equals the mind of the Bodhisattva. Koan practice teaches us to wait in the shadow of the cloud of not-knowing—looking where nothing can be seen, listening where nothing can be heard. Over time we understand that all solutions come to us on their own from the source of being, when we stop trying to control. The secret is trust. If we trust ourselves enough to not know, then we learn how to trust the shining ability to create the Tao—universal mind.
