雲門匡真禪師廣錄 2.87

2.87

The Master sometimes said, "Explaining horizontally and explaining vertically about bodhi, nirvāṇa, tathatā, and Buddha-nature—all of this is downward deliberation. Even at the moment of taking up the mallet and raising the whisk, that too is explaining horizontally and explaining vertically; compared to what went before, it is only slightly better." A monk asked, "We invite the Master to speak of what is transcendental." The Master said, "The assembly has been standing a long time; quickly make three bows."
