@senshin Okay so that question can actually take a lot of forms. Deciding how to handle them might actually take a bit of expertise in Hinduism that I can't offer, but a couple patterns I've seen on C.SE go like this:
If they are realy asking as science question (e.g. is there a scientific reason for X) then they are off topyic. Either skeptics for myth busting or one of the science sites for analysis of a known phenomenon.
On the other hand a lot of time what they have in mind is a doctrinal question and science can ether play along or not (e.g. what does group X believe about phenomenon Y). That's a doctrinal question about a specific group and answerable on C.SE as is. They might or might not cite science and they might be right or wrong in their use of it, it really doesn't matter. The question is about the beliefs of X, not science.
Of course the problem is people usually think they are asking the former when really they are asking the latter, and people assume they are answering the former when they aren't and everything goes haywire. Sorting out which is which is really a case by case thing and I find you have to edit the questions to be very explicit and then insist answers stay in that scope.
Does that make any sense? Obviously the intersection between disciplines is going to be very different for H that it is for C and you will have to figure out how to break that down for your context, but the issues with the SE format might be similar.
