次科，但列五緣無罪，則顯餘二有罪。第一以輕易重，有罪可知。第三對處，何得有罪。此謂三礙後生，或容離犯，非一向無故。

Under the next heading: listing only five causes as without offense thereby indicates that the remaining two incur offense. In the first, exchanging a light [offense] for a heavy one incurs offense, which is understandable. In the third, "Facing the Location", how could there be an offense? This refers to the three obstructions subsequently arising, where separation may perhaps incur an offense; it is not entirely nonexistent.
