6.26

「是故因可燃」下，第三因不因門破。上半因無因破燃、下半破可燃。此門二意故來：一者結上，因門逐近結相待四偈，不因結前一異諸偈。又因結上相待，不因破其絕待也。

From "Therefore, dependent on fuel" downward is the third approach: refutation by means of dependent and independent. The first half refutes fire through dependent and independent; the second half refutes fuel. This approach comes for two reasons: first, to conclude the above—the 'dependent' approach closely concludes the four verses on mutual dependence, while 'independent' concludes the preceding verses on identity and difference. Second, 'dependent' concludes the above mutual dependence, while 'independent' refutes absolute independence.
