2.136

道諦下四行：一、道行者，觀五不受陰、三十七品等道能通至涅槃，名道。二、正行者，觀五不受陰、三十七品等道非顛倒法，故名正。三、跡行者，觀三十七品等道是一切聖人去處，故名跡。四、乘行者，觀三十七品等道能運行人必至三解脫，愛、見等煩惱不能遮，故名乘。

The four aspects under the truth of the path: 1. The aspect of the path: contemplating that the paths such as the five unappropriated skandhas and the thirty-seven aids can lead through to nirvāṇa; hence it is called the path. 2. The aspect of correctness: contemplating that paths such as the five unappropriated skandhas and the thirty-seven aids are non-perverted dharmas; hence it is called correctness. 3. The aspect of the trail: contemplating that paths such as the thirty-seven aids are the place to which all noble ones go; hence it is called the trail. 4. The aspect of the vehicle: contemplating that paths such as the thirty-seven aids can carry the practitioner infallibly to the three gates of liberation, unobstructed by afflictions such as craving and views; hence it is called the vehicle.
