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

"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."
