I think this is so amazing, or perhaps it was fated. My mom is a staunch follower of her religion. On our way to Hong Kong, it became apparent that the lady who sat next to her on the plane strictly practices hers. Faking sleep to avoid conversation and listening, I came to this realization.
I thought : religions are like university courses. Everyone goes through foundation modules (rights and wrongs and social norms) and eventually went on to specialize under different professors, taking different electives. And thus the many many religions.
