仁王般若經疏 3.54

3.54

"At that time, the Buddha, for the kings..." onwards is the fourth [major section] in the chapter, the supernatural power displaying the five inconceivables, which comprises five distinctions: First, the inconceivable flower transformation: that one flower enters into immeasurable ones is the few entering the many; that immeasurable ones enter into one is the many entering the few; hence both are inconceivable supernatural powers. Second, the inconceivable buddha-lands: immeasurable buddha-lands enter into a single buddha-land, because it can transform many lands to enter into one land. Third, the inconceivable hair-pores, because the small can contain the great. Fourth, the inconceivable greatness of Sumeru, because the many can enter into a mustard seed. Fifth, the inconceivable sentient beings, because immeasurable sentient beings enter into a single buddha-body. That these five supernatural powers are termed 'inconceivable' is another name for the correct contemplation of aprāptitva.
