8.390

解即有五。初辨自性，昔遠公云：願與發心有何異耶？解云：要菩提果自屬名願，作意趣向名為發心。若作此解，願與發心二法令別，違此論說最初發心以願為體。又餘經論皆云發四弘願名為發心。

The explanation has five [points]. The first clarifies its intrinsic nature. Formerly, Master Yuan said: What difference is there between the vow and generating the mind? The explanation says: Longing for the fruit of bodhi to belong to oneself is called the vow; paying attention to head toward it is called generating the mind. If one offers this explanation, the two dharmas of vow and generating the mind are made distinct, which contradicts this treatise's statement that the initial generation of the mind takes the vow as its substance. Furthermore, other sūtras and treatises all say that making the four great vows is called generating the mind.
