四分律行事鈔資持記 2.1097

2.1097

第六緣中，初引《善見》五足。前二乃是轉別成僧，故免別過；下三並謂眾不滿四，非別可知。第五注中，恐濫病時，故特簡之。以病但開己，狂等開他故也。

In the sixth condition, it first cites the five sufficient cases from the Sudarśanavinayavibhāṣā. The first two transform a separate group into the saṃgha, and therefore avoid the fault of separation; the latter three all mean that the assembly does not complete four, so that it is not a separate group can be known. In the commentary on the fifth case, fearing confusion with the time of illness, it specially sifts it out: because illness only grants an exception for oneself, whereas insanity and the like grant exceptions for others.
