仁王般若經疏 2.39

2.39

Regarding the four aspects of the Ninth Bhūmi: First, from "abides in a hundred thousand koṭis" onward, it clarifies the lands where transformation takes place. Second, from "becoming a king of the Third Dhyāna" onward, it clarifies the marks of superior rebirth. The Bhūmi-sūtra states, "becomes a Brahmā king, ruling over two thousand realms;" the Yingluo jing says, "becomes a king of the Śuddhāvāsa devas." Third, from "cultivates a hundred thousand koṭis" onward, it clarifies the Dharma gates that are known. Fourth, from "four unobstructed knowledges" onward, it clarifies the marks of practicing benefit for others, which is using the four analytical knowledges to transform sentient beings.
