This time of year always give me pause to consider the elements that have gone into present day religion and how such processes may affect western Buddhism in the future.
Lets take the most obvious - Christmas. As a Christian holidayit has elements of Germanic Yule, Latin Saturnalia and Celitc Solstice observances along with traditional Christian tradition. You could, if you wanted, throw Mithraism and Egyptian mythos into the mix.
The process by which this happened was first described to me as Purposive Evolution. Simply put, this is a status quo, like Germanic religions, encounters a revolutionaryforce in Christianity. Conflict arises. The result is something new arises, containing elements of both the status quo and the revolutionary.
This is why eastern and western christianity differ. This is why they are in some ways the same. The same is said for Buddhism. As Buddhism spread it encountered new cultures and was adapted by those cultures. Sometimes Buddhism prevailed, sometimes not.
This makes defining "pure" religions difficult because they are all have strong cultural influences and all the a]way back. Like Christianity. Christianity has Judaism as it's basis. Judaism contains elements of Mesopotamian and Egyptian mythology. The same goes for whatever flavor of Buddhism you care to name.
You often see discussions about the future of western Buddhism. These commonly about what people think should be added or subtractedas if there could be a collectively conscious decision to make. It doesn't work that way. Like the Chridtmas tree. This tradition is about as non-Christion as it gets, yet there is is in Chistian homes world-wide. There was no meeting to add that to Chritian tradition, it just worked its way in. Why? Because it worked. Tibetan Buddhism is a fusion of Bon and Tantric Buddhism.
Sadly, none of us will live long enough to seewhat Western Buddhism will be, but it's still fun to speculate.
Personally I thing Buddhism in the west will begin with a fusion with monastic/contemplative Chistianity.
