唯識二十論述記 1.8

1.8

次辨機者，有情根性總有五種：謂三定性、一不定性、一總無性。於此五中，唯大乘定及不定性之所聽受，非餘聲聞、獨覺等性之所依信。《成唯識》云「無性有情，不能窮底」、「趣寂種姓，不能通達」，所辨教理，無上乘故，說唯有一心，無心外境故。舍利弗等，如聾、盲故，如成唯識義疏中說。

Next, to distinguish the capacities: the faculties and dispositions of sentient beings generally comprise five kinds: the three determinate dispositions, one indeterminate disposition, and one entirely lacking in disposition. Among these five, it is heard and accepted only by those of the determinate and indeterminate dispositions of the Mahāyāna, and is not something upon which the remaining dispositions of śrāvakas, pratyekabuddhas, and so forth can rely with faith. The Cheng weishi lun states: 'Sentient beings lacking disposition cannot plumb its depths,' and 'Those of the lineage inclined to extinction cannot penetrate it,' because the doctrine and principles set forth belong to the unsurpassed vehicle, and because it teaches that there is only the one mind and no objects outside the mind. Śāriputra and the others were like the deaf and blind, as explained in the Commentary on the Meaning of the Cheng weishi lun.
