楞伽阿跋多羅寶經註解 1.621

1.621

不定種性者，聞說聲聞、緣覺、如來三種法時，隨生信解而順修學，從小入大，其性可移，故言不定。初治地者，即乾慧地人，為其說不定種性，令彼超入無所有地，此地即第七已辦地。作是建立者，作是說也。彼自覺藏等者，《入楞伽》云：「彼住三昧樂聲聞，若能證知自所依識，見法無我，淨煩惱習，畢竟當得如來之身。」自所依識即自覺藏，第八識也。煩惱習即無明也。

"Indeterminate lineage" means that when hearing the three dharmas of the Śrāvaka, Pratyekabuddha, and Tathāgata expounded, they give rise to faith and understanding accordingly and practice and study in conformity, progressing from the small to the great; because their disposition can be shifted, it is called "indeterminate." "Stage of initial purification" refers to persons on the stage of dry wisdom; the indeterminate lineage is expounded for them to cause them to transcend and enter the stage of nothingness, which is the seventh stage, the stage of completion. "Established in this way" means taught in this way. As for "that personal awakening treasury," and so forth, the *Ru Lengqie* says: "Those Śrāvakas dwelling in the bliss of samādhi, if they can realize and know the consciousness upon which they rely, see the selflessness of dharmas, and purify their habitual tendencies of affliction, shall ultimately attain the body of the Tathāgata." The consciousness upon which one relies is the personal awakening treasury, the eighth consciousness. The habitual tendencies of affliction are avidyā.
