妙法蓮華經玄義 1.140

1.140

二、辨相者，世界如車，輪、輻、軸、輞和合故有車，無別車也。五眾和合故有人，無別人也。若無人者，佛是實語人，云何言：「我見六道眾生」？當知有人。

Second, discerning the characteristics: The world is like a cart; because wheels, spokes, axle, and rim assemble together, there is a cart, and there is no separate cart. Because the five aggregates assemble together, there is a person, and there is no separate person. If there were no person, since the Buddha is one who speaks the truth, why would he say, "I see sentient beings of the six destinies"? One should know that there is a person.
