The founding moment of Chan. A flower, a smile, and the origin of "mind-to-mind transmission."

02
心物 · Mind & Object

Wind and Banner

风幡之议

Huineng's epistemological revolution: "It is not the wind that moves. It is your mind that moves."

03
因果 · Karma

Baizhang's Fox

百丈野狐

"Does not fall into cause and effect" vs. "does not obscure cause and effect." A single word, five hundred lives.

04
话头 · Hua Tou

Go Drink Tea

吃茶去

Zhaozhou's answer to everyone, regardless of their experience: "Go drink tea."

07
二元 · Duality

南泉斩猫

The monks argue. Nanquan cuts. Zhaozhou puts sandals on his head. The cost of duality.

08
传承 · Lineage

俱胝竖指

The attendant copies the gesture. The master cuts off the finger. What survives the cutting is real.

09
亵渎 · Transgression

The Dry Shit Stick

干屎橛

"What is Buddha?" "A dry shit stick." The highest offense against the sacred — and the most liberating.

10
手段 · Method

德山棒 / 临济喝

"Speak and get thirty blows. Don't speak and get thirty blows." The nature of the blow and the shout.

香严上树

Hanging by your teeth. Speak and die. Stay silent and fail. What do you do?

Wumen's closing verse. If you carry no idle concerns in your mind, every season is the best season.

13
本来面目 · Original Face

Neither think good, nor think evil. Right at this moment — what is your original face before your parents were born?

丹霞烧佛

Freezing cold. Danxia burns a wooden Buddha for warmth. "If there are no relics, bring me two more to burn."

15

A pebble strikes bamboo. "One strike — and I forgot all I ever knew." Knowledge versus direct experience.

16

即心即佛 / 非心非佛

Mazu's dialectic: first a pacifier, then a disease. "It is not mind, it is not Buddha."

"What is Buddha?" "Three pounds of hemp." The sacred and the mundane weigh the same.

21

Baizhang Rolls Up the Mat

Words like a blade. Gate steep and fierce. The monk shouts; Muzhou strikes. No performance accepted.

疑情 · The Mass of Doubt

Dahui's Kan-Hua Chan

From seeking the ox to entering the marketplace with open hands — Chan's most systematic map of the spiritual journey.
