仁王般若經疏 3.53

3.53

時佛為王現五不思議神變：一華入無量華、無量華入一華，一佛土入無量佛土、無量佛土入一佛土，無量佛土入一毛吼土、一毛吼土入無量毛吼土，無量須彌無量大海入芥子中，一佛身入無量眾生身、無量眾生身入一佛身，入六道身、入地水火風身，佛身不可思議、眾生身不可思議、世界不可思議。

"At that time, the Buddha displayed five inconceivable supernatural transformations for the kings: a single flower entered into immeasurable flowers, and immeasurable flowers entered into a single flower; a single buddha-land entered into immeasurable buddha-lands, and immeasurable buddha-lands entered into a single buddha-land; immeasurable buddha-lands entered into a single hair-pore land, and a single hair-pore land entered into immeasurable hair-pore lands; immeasurable Sumerus and immeasurable great oceans entered into a mustard seed; a single buddha-body entered into immeasurable sentient-being bodies, and immeasurable sentient-being bodies entered into a single buddha-body, entering into the bodies of the six destinies and entering into the bodies of earth, water, fire, and wind. The buddha-body is inconceivable, the sentient-being body is inconceivable, and the world is inconceivable."
