42.70

天祐元年。誕節勅天下寺觀設齋。民間禁屠釣○呂洞賓遊華山。遇鐘離權授金丹及劍法。後過鄂州黃龍山。值機禪師上堂（清源八世）毅然問曰。一粒粟中藏世界。半升鐺內煮山川。此意何如。師曰。守屍鬼。洞賓曰。爭柰囊中有不死丹。師曰。饒經八萬劫終是落空亡。賓不服。夜飛劍以脇之。師已前知。以法衣蒙頭坐方丈。劍遶數匝。師手指之即墮地。賓前謝過。師詰之曰。半升鐺內即不問。如何是一粒粟中藏世界。賓忽有省。乃述偈以為謝曰。自從一見黃龍後。始覺從前錯用心（仙苑遺事）。

In the first year of the Tianyou era, an imperial decree for the imperial birthday ordered the monasteries and abbeys throughout the empire to provide vegetarian feasts, and forbade slaughter and fishing among the populace. Lü Dongbin traveled to Mount Hua, where he met Zhongli Quan, who transmitted to him the golden elixir and the method of the sword. Later, passing through Mount Huanglong in Ezhou, he encountered Chan Master Ji ascending the hall (eighth generation under Qingyuan). Resolutely, he asked, "'A single grain of millet conceals the universe; / half a pint cauldron boils the mountains and streams.' What does this mean?" The master said, "You corpse-guarding ghost!" Dongbin said, "What of the fact that in my pouch is the elixir of immortality?" The master said, "Even if you pass through eighty thousand kalpas, in the end you will fall into emptiness and demise." Dongbin would not yield. That night, he flew his sword to threaten him. The master, knowing beforehand, covered his head with his Dharma robe and sat in the abbot's quarters. The sword circled several times; the master pointed his finger at it, and it fell to the ground. Dongbin came forward to apologize. The master questioned him, "Setting aside the boiling within the half-pint cauldron, what is the single grain of millet concealing the universe?" Dongbin suddenly experienced awakening, and composed a gāthā in gratitude, which went: "Ever since I once met Huanglong, / I only then realized that before, I applied my mind wrongly" (from Surviving Matters of the Immortals' Garden).
