瑜伽師地論略纂 12.121

12.121

論云「依緣起智能引發空、無願、無相解脫門」者，觀緣起生滅故，無我故，是空行；以有生滅無常流轉道理，及斷之得無為故，名無相行；以是有漏有為深可厭壞，不生希願故，名為無願。是此中意也。

Regarding the treatise stating 'based on the wisdom of pratītyasamutpāda, one can induce the liberation doors of emptiness, wishlessness, and signlessness': Because one contemplates the arising and cessation of pratītyasamutpāda, and because of selflessness, it is the practice of emptiness. Because there is the principle of the impermanent transmigration of arising and cessation, and by severing it one attains the unconditioned, it is called the practice of signlessness. Because conditioned and contaminated things are deeply repulsive and destructible, so that no longing or wishing arises, it is called wishlessness. This is the meaning here.
