Is that crude? Something closer to truth, aligned with the latest in science, not something set in stone (or in books), always open to improvements, without any anthropomorphic characterization which leads to conflicts. I think anthromorphic characterization with avataras, sons, messengers, prophets, mahdis, manifestations is the one which is crude and not suited to 21st Century. There is no grand-daddy in the sky, no heaven, no hell, no judgment, no rebirth, no resurrection. Why fool ourselves? It is one life that we have, which should be lived wisely. We arise from Brahman and dissolve back again in Brahman. And that is it.
