7.165

第十解瑜伽所作中，景師釋云：所依滅及轉者，由修瑜伽作意令自相續中麁重身滅輕安身起。謂或有遍知所緣愛樂所緣與所依滅轉而為上首等者，謂由遍知理事所緣及愛樂觀彼理事所緣，故能於身令滅令轉。或有遍知所緣愛樂所緣用所依清淨為上首等者，前說由二所緣令身滅轉，今時復由所依輕安轉故，令此遍知所緣愛樂所緣得善清淨。

In the tenth section, explaining the work of yoga, Master Jing interprets: regarding "the destruction and transformation of the basis": through cultivating the mental engagement of yoga, coarse heaviness in one's own continuum is destroyed and a body of pliancy arises. Regarding "there is thorough knowledge of the object and delighting in the object serving as the foremost for the destruction and transformation of the basis, etc.": it means that through thoroughly knowing the objects of principle and phenomena and delighting in observing those objects of principle and phenomena, one is able to effect destruction and transformation in the body. Regarding "there is thorough knowledge of the object and delighting in the object using the purification of the basis as foremost, etc.": previously it was said that due to the two objects one effects destruction and transformation in the body; now, furthermore, because the basis transforms into pliancy, it causes this thorough knowledge of the object and delighting in the object to attain excellent purity.
