I believe Salinger briefly studied Vedanta in ny in the late 40's/early 50's but I forgot the name of his swami...I think that looking for buddhism in catcher may be a bit like asking where the ducks go... and I also think looking closely at how holden interacts with nuns can tell us plenty about a modern take on christianity but what tells me most is how holden embraces some of the best beliefs of all religions--I think he's really a quite holy fellow when you know him closely, but I also think holiness has much less to do with organized religion than they would have us believe...will ps: jon's advice is right on but I don't suggest sending teachers anonymous notes--as a teacher myself, I believe separating identity/humanity from thinking just doesn't make sense, even for stuffy academics like I sometimes am...so instead of an anonymous note, a polite one with honest thinking might be preferred...
