瑜伽師地論略纂 8.96

8.96

Regarding the treatise: "All dauṣṭhulya is entirely pacified; following that, one touches and realizes, and the basis (āśraya) is purified," and so forth: this explains the four purifications: first, purification of the body, here called the basis; second, the objective support (ālambana); third, the mind; fourth, the purification of knowledge and vision.
