Is it possible to be part of two different religions or cultures at the same time?
I think the real issue would be which of those religions is true, and while certain religions may be associated with particular cultures (e.g., Hinduism in India), religions typically aren’t confined to just a single culture. Your life could incorporate any number of influences from various cultures, but just because a number of different religions may seem intriguing, not all of them necessarily contain the ultimate truth about God, life and eternity. Focus first on finding truth–I believe that Jesus Christ is the only way to get to God–and then the cultural aspects will eventually be worked out.
