Nature is interested in only two things-to survive and to reproduce one like itself. Anything you superimpose on that, all the cultural input, is responsible for the boredom of man. So we have varieties of religious experience. You are not satisfied with your own religious teachings or games; so you bring in others from India, Asia or China. They become interesting because they are something new. You pick up a new language and try to speak it and use it to feel more important. But basically, it is the same thing.
