13.76

五所成行亦三種，謂一十度中當方便善巧行；二當地成就雙行無相行，謂則空方便智發起有中殊勝行；三學無功用行，如此下文說。及《莊嚴論》第七住雖行功用，而上參一道多住無相故。

Fifth, the practices accomplished are also of three kinds: first, among the ten pāramitās, it corresponds to the practice of skill-in-means (upāyakausalya); second, in this bhūmi one accomplishes the dual practice of marklessness, meaning that through the upāya-knowledge of emptiness one generates superior practices within existence; third, one trains in effortless practice, as explained below, and as the Mahāyānasūtrālaṃkāra states, although the seventh stage practices with effort, it touches upon the single path above and abides mostly in marklessness.
