南宗頓教最上大乘摩訶般若波羅蜜經六祖惠能大師於韶州大梵寺施法壇經 1.53

1.53

又有一僧名神會，襄陽人也。至漕溪山禮拜，問言：「和尚坐禪，見亦不見？」大師起，把打神會三下，却問神會：「吾打汝，痛不痛？」神會答言：「亦痛亦不痛。」六祖言曰：「吾亦見亦不見。」神會又問：「大師何以亦見亦不見？」大師言：「吾亦見，常見自過患，故云亦見。亦不見者，不見他人過罪，所以亦見亦不見也。汝亦痛亦不痛如何？」神會答曰：「若不痛，即同無情木石；若痛，即同凡夫，即起於恨。」大師言：「神會！向前！見不見是兩邊，痛不痛是生滅。汝自性且不見，敢來弄人？」神會禮拜，再禮拜，更不言。大師言：「汝心迷不見，問善知識覓路；汝心悟自見，依法修行。汝自迷不見自心，却來問惠能見否？吾不自知，代汝迷不得；汝若自見，代得吾迷？何不自修，問吾見否？」神會作禮，便為門人，不離漕溪山中，常在左右。

There was also a monk named Shenhui, a native of Xiangyang. He came to Caoxi Mountain, bowed in homage, and asked, "When the Reverend sits in dhyāna, do you see or do you not see?" The Master stood up, struck Shenhui three blows, and then asked Shenhui, "When I strike you, does it hurt or not?" Shenhui answered, saying, "It hurts, and yet it does not hurt." The Sixth Patriarch said, "I both see and do not see." Shenhui asked again, "Why does the Master both see and not see?" The Master said, "I see: I constantly see my own faults and errors, therefore I say I see. That I do not see: I do not see the faults and sins of others; therefore I both see and do not see. How is it that you both hurt and do not hurt?" Shenhui answered, saying, "If it did not hurt, I would be the same as insentient wood or stone; if it hurt, I would be the same as an ordinary person, and resentment would arise." The Master said, "Shenhui! Step forward! Seeing and not seeing are the two extremes; hurting and not hurting are arising and ceasing. When you do not even see your own-nature, how dare you come to play games with someone?" Shenhui bowed in homage, bowed again, and spoke no further. The Master said, "If your mind is deluded and does not see, ask a kalyāṇamitra to seek the path; if your mind is awakened and sees on its own, practice according to the Dharma. You yourself are deluded and do not see your own mind, yet you come to ask whether Huineng sees or not? If I know for myself, I cannot take the place of your delusion; if you see for yourself, could you take the place of my delusion? Why do you not cultivate it yourself, instead of asking whether I see or not?" Shenhui paid homage and became a disciple, not leaving Caoxi Mountain and constantly remaining by his side.
