瑜伽師地論略纂 6.15

6.15

第十、《蕩塵經》中，文有三：初、引經問；二、釋三陶練；三、舉法合。　「如金性內所有生金」下，是發心出家，名初陶練；在資糧道位，得靜慮等，是次陶練；入聖位已，是後陶練，故論說言「不為有行之所拘執」。依慧根伏，令根姓顯，根除煩惱，立陶練名。

Tenth, in the Sūtra on Cleansing Dust, the text has three parts: first, citing the sūtra and questioning; second, explaining the three refinements; third, presenting the dharma-analogy to match. Below 'just as raw gold existing within gold-nature,' this is generating the intention to leave household life, called the initial refinement; at the stage of the path of accumulation, obtaining dhyāna and so on, this is the second refinement; having entered the noble stage, this is the final refinement, which is why the treatise states: 'is not constrained by conditioned practices.' Depending on subduing through the faculty of wisdom, causing the disposition of faculties to become evident, and eliminating afflictions at the root, the name 'refinement' is established.
