四分律行事鈔資持記 3.578

3.578

引證中，《智論》，初明佛讚意。道行，即通三乘聖道；世樂，即五欲苦因。四依，頭陀是根本制；望後開教，故云為本。有下，示開聽。言因緣者，即中下機，生衣食房藥四種開教，皆有緣故。不得已者，非聖意故。餘事者，通指一切聽教也。

In citing proofs: the Da zhidu lun first clarifies the Buddha's intent in his praise. "Path practice" encompasses the holy paths of the three vehicles; "worldly pleasure" is the painful cause of the five desires. The four reliances and the dhūtas are the fundamental proscriptions; looking ahead to the later permissive teaching, it therefore says they "serve as the foundation." From "There are..." below, it shows the exceptions and permissions. The words "causes and conditions" mean that for the middling and inferior faculties, the arising of the four kinds of permissive teachings—robes, food, dwellings, and medicines—all have conditions. "When there is no alternative" is because it was not the sage's original intent. "Other matters" refers generally to all permissive teachings.
