What a wonderful experience for you. I always believe it is God. Some people believe a higher power. As to Religion. I think only you can decide. I was raised Catholic but have attended several different churches over the years. Some I found very judgemental. Some would rather Preach than, Walk the Walk". When you find a place where people are loving, accepting, and leave you free to experience whats in your heart I think its a place to consider. First Nations have conections to nature. What is interesting to me is whatever religion you look at the basics are the same.
