I was also speaking of local interpretations and admixtures of older folk things thrown in, but did a fair amount of study of Buddhism as a younger guy, and as with Chinese Chan and Japanese Zen, quite respective of all life.....but worldwide, no matter the religion, as it spreads, local adaptations and even corruptions take place until in some places, very little remains of the original.....even where it stays relatively sound, human nature takes its toll and there are going to be forever the need for renewal and need for purifying what has become corrupt....
But i had noticed in the old writings of Bill, the differences between shop 1 and shop 2 with shop 1 more a thing with workers and environs seemingly more Hindu and also a really nice assortment of critters dedicated and then the feast, while shop 2 more seeming the Buddhist side of things.....or might be simply rural vs more cosmopolitan so to speak, but quite a bit of difference...
As a student of religion, i found it quite fascinating....and this is not only an eastern thing as witness how in some places western religions out in the hinterlands of far continents have gone so "local" as to hardly show even a sign of the western religion among all the local festivities, and one would be hard pressed to tell it from an eastern local festival......and so it will go until everything is rolled up like a carpet....
