The rules of the meme are to list three religions, apart from your own, that you find fascinating and why.I'd probably find it easier to list the religions I can't stand. But as per the question, here are the three religions I would try out if I had my druthers:
1. Sikhism. Sikhism just seems to me to be a very sensible religion with some very sensible ethical principles. For example, I like that a Sikh temple (a gurdwara) is always ready to receive visitors (of any faith) and feed them.
2. Hinduism. Its worship is a colourful, vibrant experience. You get to make lots of noise and eat lots of fruit and nuts. Its temples and deities are stunningly beautiful works of art. Frankly, Hinduism is fun.
3. Buddhism. Since it's the one major world religion that doesn't require belief in a deity, in the traditional sense, perhaps this is the one for me. I think learning the disciplines of Buddhist life, eg meditation, could be quite fruitful.
I'm aware my reasons don't appear particularly deep. They may even come across as offensive, especially the suggestion that I should try Hinduism because it's fun to make noise, look at pictures and eat stuff. I think there's something much more profound lurking beneath those statements, but I'd probably need to sit down and talk it all through for it to emerge.
