首楞嚴義疏注經 3.374

3.374

破月生也。前五句正牒破，月去人間如日之量，故云遠方。月光照處皆合成流，何獨珠出？流則下四句雙結非也，照處皆流，何用珠出。設無流者，顯此水性不從月來。

This refutes arising from the moon. The first five lines directly take up the refutation. The moon's distance from the human realm is like that of the sun, hence it is called 'a distant place'. Everywhere illuminated by moonlight ought to form streams; why only from the pearl? The four lines beginning with 'if they pour forth' jointly conclude that it is not so: if everywhere illuminated forms streams, what need is there for it to come from the pearl? If there are no streams, this shows that the nature of this water does not come from the moon.
