[Master Dogen related a] story about two Chinese Zen masters, Shigong Huizang (n.d.; Shakkyo Ezo in Japanese), and his younger Dharma brother, Xitang Zhizang (735-814; Seido Chizo in Japanese). Shigong asked
Do you know how to grasp space? The younger brother, Zhizang said
Yes I do. Shigong asked
How do you grasp it? Zhizang stroked the air with his hand. Shigong said
You don't know how to grasp space. Zhizang asked
How do you grasp it, older brother? Shigong grasped his younger brother's nose and yanked.
[It might even be read that he stuck his finger in the younger brother's nostril before pulling ..] Either way, Zhizang yelled in pain:
You're killing me! You tried to pull my nose off!
Since you like music, my friend, I refer you to Laurie Anderson .. ;) Shigong said
You can grasp it now!
