瑜伽論記 5.142

5.142

三云：有漏惠是加行道；二、缺諸煩惱無間道；三、缺諸事解脫道，除諸麁重及果法故；四、為無餘斷諸煩惱事故，如前所得轉更修習是勝進道。

The third says: Tainted wisdom is the path of preliminary application; second, lacking afflictions is the uninterrupted path; third, lacking various matters is the path of liberation, because it eliminates crude heaviness and resultant phenomena; fourth, for the sake of severing without remainder the matters of various afflictions, cultivating further in accordance with what was previously attained is the path of superior progress.
