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 1.38

1.38

「善知識！後代得吾法者，常見吾法身不離汝左右。善知識！將此頓教法門，同見同行，發願受持，如是佛教，終身受持而不退者，欲入聖位，然須傳授，從上以來，默然而付衣法，發大誓願，不退菩提，即須分付。若不同見解，無有志願，在在處處，勿妄宣傳，損彼前人，究竟無益。若愚人不解，謗此法門，百劫千生，斷佛種性。」

"Kalyāṇamitras! Those who attain my Dharma in future generations will constantly see my dharmakāya not departing from your side. Kalyāṇamitras! Taking this Dharma-gate of the sudden teaching, sharing the same view and the same practice, make vows to uphold it; upholding such teaching of the Buddha throughout your life without backsliding, you will enter the stage of sages. Then it must be transmitted: from the past down to the present, the robe and Dharma have been silently conferred; when someone makes a great vow and does not backslide from bodhi, it must be handed over. If they do not have the same understanding and do not have the aspiration, do not recklessly propagate it everywhere, which would harm those who came before and ultimately be of no benefit. If foolish people do not understand and slander this Dharma-gate, for a hundred kalpas and a thousand lifetimes they will cut off the gotra of the Buddha."
