說無垢稱經疏 5.462

5.462

贊曰：七希也。內見法身、外觀報佛，況化身利物，何求不至。故至心祈請，應念則來；感切希法，聞已而去。總十一佛。

Commentary: The seventh rarity. Internally seeing the dharmakāya, externally observing the saṃbhogakāya Buddha; how much more so for the nirmāṇakāya benefiting sentient beings—what request would not arrive? Therefore, praying with utmost sincerity, they arrive in an instant of thought; feeling deeply and aspiring for the Dharma, having heard it, they depart. There are eleven Buddhas in all.
