釋禪波羅蜜次第法門 10.52

10.52

When the practitioner deeply contemplates the internal bones, they then see light universally illuminating the ten directions; illuminated by the light, all the skeletons also become bright and pure. When this contemplation is accomplished, toward all enemies, loved ones, and neutral persons, as well as all pleasant and ugly [forms], their mind is equal, without attachment or hostility; this is called mastering knowledge and mastering vision whether pleasant or ugly. The meaning of mastering knowledge and vision of pleasant and ugly is as explained before.
