佛說仁王般若波羅蜜經 2.21

2.21

The Great Sage said: “There are good sons who practice the contemplation-gates of the thirteen [levels of patience] and are great Dharma kings. From the patience of habituation up to the diamond summit, they are all dharma masters on whom [the world] relies and depends. You, the great assembly, should make offerings to them just as you would offer to a buddha, bringing millions of billions of heavenly flowers and heavenly incense to present to them.
