仁王般若經疏 2.33

2.33

六地四者，初住十萬億佛國下，明所化土。二作他化天王下，明增上生相。《地經》云「作化樂天王」，瓔珞經同此經云「作他化天王」。三修十萬億法下，明所知法門。四十二緣下，明利他行相，自知十二教化令知。

For the sixth ground, the four are: first, from "abides in a trillion buddha-lands" onward, clarifying the land to be transformed. Second, from "acts as the king of Paranirmitavaśavartin Heaven" onward, clarifying the characteristics of superior rebirth. The Daśabhūmika-sūtra says: "acts as the king of Nirmāṇarati Heaven"; the Yingluo jing agrees with this sūtra in saying: "acts as the king of Paranirmitavaśavartin Heaven." Third, from "cultivates a trillion dharmas" onward, clarifying the known dharma-gates. Fourth, from "twelve links" onward, clarifying the characteristics of practice to benefit others: knowing the twelve [links] oneself and teaching to cause others to know them.
