What does enlightenment actually entail in Shugendo?

We already have some questions about enlightenment, but this is going to be a bit more... esoteric. What I would like to know is what enlightenment entails in Shugendo , which is a particularly syncretic variety of Japanese Buddhism. What with Shugendo being strongly syncretized with the native animistic practices of Japan (i.e. Shinto), it appears that the notion of enlightenment has somehow become intertwined with the idea of _kami_ (spirits/deities). Specifically, it appears (from some basic reading) that a practitioner of Shugendo (a _shugenja_) attains enlightenment when he "becomes one" with the _kami_ in some sense. This is quite unlike many other varieties of Buddhism - after all, in most cases, there are no _kami_ to begin with! In any case, this is all very vague, so I was hoping somebody could clear this up for me - what, exactly, does enlightenment entail in Shugendo?
