瑜伽師地論略纂 11.165

11.165

論云「四、於善友若正依止，於如法義若合若離，隨自在轉」等者，謂所依止師說法，若與舊同名合，若別名離；或依經論等合，等若別出兼見不依經等名離。曲如法之見也，隨師自在，而不傾動。又自性名合，差別名離。又合者，即令此義相符，如因明中合等；若離者，令此義別，如因明中離等。

When the treatise states, "Fourth: properly relying upon a spiritual friend, whether conforming to or diverging from the teaching according with the Dharma, adapting freely to them", and so forth, it means: when the teacher upon whom one relies expounds the Dharma, if it agrees with the past, it is called "conforming"; if it is different, it is called "diverging". Or, relying upon the sūtras, treatises, etc., is "conforming"; if he presents an alternative interpretation alongside his own view that does not rely on the sūtras, etc., it is called "diverging"—a distorted view of conforming to the Dharma, yet one adapts freely to the teacher without wavering. Furthermore, intrinsic nature is called "conforming", and particular differences are called "diverging". Moreover, "conforming" means making these meanings accord, like application in hetuvidyā; "diverging" means making these meanings distinct, like counter-application in hetuvidyā.
