Oh sorry, missed the point. Yes, incorporation sure, but then we incorporate bits of everything into paganism - Wicca for example is a mish mash of every Eastern religion going, dash of Theosophy, bit of British folklore, this that and the other, so yet. I use stuff from all over, most people do because, let's face it, being honest here, what else we got?
But the above book still stands

Problem is, Buddhism tends to make paganism obsolete lol I find the two are at loggerheads in my soul. Why i'm not a Buddhist I s'pose

But yes, an exchange of cultures and ideas is enriching most of the time.
