大般涅槃經義記 4.194

4.194

就法寶中，「或復說言正法當滅」合索先陀。正法滅中備含多義，雖有多義統名法滅故似先陀。「智臣應」下合奉鹽等，由法滅故，人多造惡，受諸苦報，故偏就之以明苦也。

Regarding the Dharma Jewel, "Or again saying that the true Dharma is about to perish" matches asking for saindhava. In the perishing of the true Dharma many meanings are fully contained; although it has many meanings, it is comprehensively called the perishing of the Dharma, hence it resembles saindhava. From "The wise minister should..." downward matches serving salt and so forth: because the Dharma perishes, people mostly create evil and suffer various painful retributions, so it especially draws upon this to clarify suffering.
