Notions of self in religions that blend Buddhism and Hinduism

I read in Peter Harvey's book an Introduction to Buddhism that there was a syncretistic religion in Bali that was a mixture of Buddhism and Hinduism. He didn't give many details as it was a very minor point. Has anyone got any details about this religion. I'm particular interested on how it deals with the notion of the self. My rudimentary understanding of Hinduism is that there is most definitely a self (atman??) whereas in Buddhism a central tenant is that there is no fixed self (anatman). The two religions seem to conflict on this point so I'm interested how this is reconciled. As a note I think there is also this kind of religion in Cambodia but I could be wrong in that.
