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 1.6

1.6

Having received their instructions, the disciples returned each to their own rooms and said to one another: "We need not clear our minds and exert ourselves to compose verses to present to the Venerable One. Senior Shenxiu is the instructor; once Senior Xiu receives the Dharma, we can naturally rely upon him. There is no need to write verses!" Everyone set their minds at rest, none daring to present a verse. At that time, in front of the Master's hall, there was a corridor of three bays. Beneath this corridor offerings were made, and they wished to paint the Laṅkāvatāra transformation tableau, as well as a record of the Fifth Patriarch transmitting the robe and Dharma to circulate in later generations. The painter Lu Zhen, having inspected the wall, was to begin work the following day.
