continual participation
This idea of embodiment through continual participation is a theme that runs throughout all of the readings - and also connects back to LPP.
The learner only becomes a master of a figured world by immersing themselves in it, first peripherally, and then more and more actively (see the descriptions in chapter 4 about the development of individual's AA story). Ultimately, if successful, they come to identify with the world and see themselves as a part of it.
