第二十相中，有四又字，初一於染污淨體相應不相應，第二又字於染淨相應不相應過患，下二又字於前第五難成辨思惟之相。

Within the twentieth aspect, the character "furthermore" (又) occurs four times: the first concerns conjunction and non-conjunction with defiled and pure entities; the second "furthermore" concerns the faults of conjunction and non-conjunction with defilement and purity; the latter two "furthermore"s concern the contemplation of the difficulty of accomplishment in the fifth [base] mentioned above.
