悬空的隔断所准的惟独在水上——那是众贤单在水上开的一层宽。何以在水上肯宽呢?那里岂不也有鱼游过么?可见鱼游过算不得「过」。

——惟独在水上。
in water.
-
那是众贤单在水上所开的一层宽,别的情形并不如此。
It is a leniency the Sages instituted in water but not in other circumstances.
-
他们何以单在水上的悬空隔断上肯宽呢?
And why were they lenient with regard to a hanging partition in water?
-
那里岂不也有鱼游过么?
Isn’t there the passage of fish?
-
可见由此断得出来:鱼游过算不得「过」。
Rather, learn from this that the passage of fish is not considered passage.
