釋禪波羅蜜次第法門 3.75

3.75

二、明背捨善根發者，亦於欲界、未到靜定心中，忽見內身不淨、胮脹、狼藉；或見自身白骨，從頭至足，節節相拄，乃至骨人光明昱燿，定心安隱，厭患五欲，不著我人。此是背捨善根發相。

2. Explaining the arising of the wholesome roots of the liberations: within a calm, concentrated mind in the desire realm or the anāgamya stage, one suddenly sees the internal body as impure, bloated, and disordered; or one sees one's own white bones, from head to foot, joint supporting joint, even to the point where the skeleton radiates blazing brilliance, while the concentrated mind is serene and stable, disgusted with the five desires, and free of attachment to self or person. These are the signs of the arising of the wholesome roots of the liberations.
