大般涅槃經義記 9.206

9.206

六不同四大令人齊得，明無聖道。於中初明四大齋等，「若有聖」下徵道同大，「然今」已下不同證無。

Sixth, it is not like the four great elements that allow people to attain them equally; this clarifies that there is no noble path. Therein, it first clarifies that the four great elements are equal; from "If there were noble [paths]" onward, it challenges that the path should be identical to the great elements; from "Yet now" onward, it uses their difference to prove non-existence.
