S.2585 is a significant Dunhuang manuscript, providing various types of Buddhist meditative techniques. Some techniques can be traced back to Central Asia and India, although some techniques seem to have been developed later. I argue that the vision of buddhas that accompanies single-minded contemplation of the navel as described in S.2585 may reflect the idea of a “buddha within” denoting the notions of buddha-nature and tathāgatagarbha in some contexts. I also argue that navel contemplation became an important part of Buddhist meditation practice in early Chinese Buddhism.
