6.475

釋中有四：一、明發三乘願別；二、明發三乘願人，一一皆通三乘根性；三、明定姓聲聞雖發獨覺及大乘願後，必定還捨獨覺及大乘願住聲聞願，定性獨覺及大乘根應知亦爾。然此文中但明定姓三乘，不明不定姓人一人成二成三乘姓，逢緣即悟彼乘聖道等者略也。四、簡取地義，云今此義中當知唯說聲聞乘願聲聞種姓等者，泰云：三乘皆有定不定性。然此義中辨聲聞地故唯說聲聞種姓，景云：唯說聲聞人願。又基云：唯取聲聞願種姓人。

Within the explanation there are four points: first, it explains the differences among the vows made in the three vehicles; second, it explains that individuals who make vows for the three vehicles each have access to the faculties and natures of all three vehicles; third, it explains that although a definite-nature śrāvaka may make vows for a pratyekabuddha or the Great Vehicle, they will definitely abandon the pratyekabuddha and Great Vehicle vows afterwards and abide in the śrāvaka vow, and one should know that those with definite pratyekabuddha and Great Vehicle faculties are also likewise (however, this text only explains the definite-nature three vehicles and does not explain people of indefinite nature where one person forms the natures of two or three vehicles, awakening to the noble path of that vehicle upon meeting conditions, and so forth, as this is abridged); fourth, selecting the doctrine of the stages, where it states: 'In the present context, one should know that it speaks only of the śrāvaka-vehicle vow, the śrāvaka gotra, and so forth.' Tai states: 'All three vehicles have both definite and indefinite natures. However, because this context discriminates the Stage of the Śrāvaka, it speaks only of the śrāvaka gotra.' Jing states: 'It speaks only of the vows of śrāvaka individuals.' Furthermore, Kuiji states: 'It takes only people with śrāvaka vows and gotra.'
