中天竺舍衛國祇洹寺圖經 2.28

2.28

Next, the fourth courtyard to the west is the Courtyard of Medical Recipes. All the medical recipes found across the worlds are collected in this quarter. There is a bronze bell shaped like a grain horn that can hold three pecks, with a golden lion as its suspension loop. When a bhikṣu enters the courtyard, the bell rings and the door opens without troubling the monastery attendant, its tone sounding like the notes of a zither. When a bhikṣu hears it, he naturally attains understanding of the smooth and obstructed paths of diverse karmas. If anyone of the third fruition or above who is ill comes and enters this courtyard, upon hearing the bell he immediately recovers; if ordinary monks are ill and hear it, they cannot be cured. The bell was crafted by Jīvaka using medicinal compounds; after the Buddha entered extinction, Jīvaka hid it away. When procuring the bronze, he selected bronze from three gates, and besides six places on the Northern Continent, he also came to Mount Niutou south of the Yangzi River in Cīnasthāna to procure it. It was synthesized using medicinal compounds.
