Monasteries and communes have not exhausted the possibilities, even if their examples can act as sources of ongoing inspiration.

修道院和公社并没有穷尽所有的可能性，即使它们的例子可以作为持续灵感的源泉。

The direct and the indirect lead on to each other in turn. It is like moving in a circle--you never come to an end. Who can exhaust the possibilities of their combination?

奇正相生，如循环之无端，孰能穷之哉！
