6.6

[52] Case: A monk asked Zhaozhou, 'For a long time I have heard of the stone bridge of Zhaozhou, but having arrived here, I only see a single-log bridge.' / Zhou said, 'You only see the single-log bridge, and do not see the stone bridge.' / The monk said, 'What is the stone bridge?' / Zhou said, 'It ferries donkeys, it ferries horses.' / (Lüe: pronounced like shi-ruo).
