 No details are given on how this process actually occurs. “Refining the bodily form in Great Darkness”, however, is similar and for some aspects identical to what many later Daoist texts call shijie, “release from the mortal body” or “from the corpse” (Robinet 1979: 57–66; Seidel 1987: 230–32; Cedzich 2001; Campany 2002: 52–60; Pregadio 2004: 121–26). After once again going through a “feigned death”, the adept departs, only to return to live in the world, typically on a mountain but at times among other human beings, in a perfected body that subsists indefinitely. A rare description of a relevant practice, found in a source originally dating from the late 3rd century, suggests that “release from the corpse” occurs in meditation. The adept is instructed to draw a talisman and to visualize himself as “being dead”. Then he takes off his clothes—an act symbolic of his forsaken personality—and walks into the mountains, never to return where he was born or lived (Cedzich 2001: 27–28; Campany 2002: 54–55). Ritual elements are also involved. The adept stages his death, and his associates (family or Daoist companions) participate in the performance: they state that his corpse has disappeared and has been replaced by other objects—typically a sword (signifying a higher form of release), a staff (signifying a lower one), or a pair of sandals (on which see Kaltenmark 1953: 40 and 52).
