法華經義記 4.60

4.60

問者言：「若無車故索，亦應無城可入，既有城可入，亦應有車可乘也。」解釋者言：「若以理惑教無車故索，若執教惑理則有城可入。是則城據逈處可以化作，車在門外可以闇說也。」

The questioner says: "If they demand because there are no carts, there should also be no city to enter; since there is a city to enter, there should also be carts to ride." The interpreter says: "If one doubts the teaching on the basis of principle, there are no carts and so they demand; if one clings to the teaching and doubts principle, there is a city to enter. Thus, based on a remote place, a city can be conjured; and since the carts are outside the gate, they can be spoken of covertly."
