This Zen language comes from the famous Zen master Niu Tau Fa Rong in Tang Dynasty. During the Yonghui period in Tang Gaozong, Zen Master Farong of Niutoushan often gave lectures at Yujianchu Temple, and the audience gathered together. One day, King Boling of Wang Zhiyi came to Youqi Temple in Niutou Mountain, asked the Zen master about Buddhism, and talked about the realm of mind.
King Boling asked Master Farong, Tauren, "Be careful, what should you do if you hide?"
Zen master Farang said, "You put your heart into it, but you don't have to. Gotama is famous for its work, but it is not heavy. Use without heart, use with heart. Today, I said that I have no intention, which is different from my intention. "
