瑜伽師地論略纂 2.129

2.129

第八、果因緣中，有二：初標四門、後隨別釋。此辨三法：一、十因；二、四緣；三、五果。親因為先，次勝為立，疎力名和合。　「內分力」，有七德。　「無事業障」者，多覺事業，名事業障。由多思覺，發諸事業，繞攘其心，癡修善品，名事業障。無此事障，名為無事業障。　「外分力」，有五德。施主資給，方得修習，故說施主名外分力。　「住正法」者，隨順為善友、不為善友，不為障難。

In the eighth section, "Fruits, Causes, and Conditions," there are two parts: first, marking the four categories, and then explaining them individually. This distinguishes three dharmas: first, the ten causes; second, the four conditions; third, the five fruits. The direct cause is the antecedent, next the superior serves as the establishment, and the indirect power is called concord. The "internal power" possesses seven virtues. Regarding "freedom from occupational hindrances": many discursive occupations are called occupational hindrances. Because of abundant reflection and discursiveness, various occupations are initiated, disturbing one's mind so that one foolishly cultivates wholesome factors; this is called an occupational hindrance. Freedom from such occupational hindrances is called freedom from occupational hindrances. The "external power" possesses five virtues. It is only when donors provide material support that one can practice; therefore, donors are spoken of as the external power. Regarding "abiding in the true Dharma": following along as a good friend, or not acting as a good friend, without being a hindering difficulty.
