Zen Buddhism
"It is said that one day Brahma lord of creation， offered the Buddha a flower and asked him to preach the Dharma. When the Buddha held up the flower， his audience was puzzled， except for Kashyapa， who smiled. This is how Zen began. And this is how it was transmitted: with a flower， with a rock wall， with a shout. This approach， once it was made known by Bodhidharma and his successors， revolutionized the understanding and practice of Buddhism in China."
