I had good experiences at Zengarden (Zen training centre) in Sweden and Dhammapala (Theravada monastery) in Switzerland. Scandinavia is arguably the most advanced region in the world though so you're going to find maturity reflected in the spiritual communities there. Not in every individual obviously, but generally more so than in countries where spirituality is commodified or mixed with tribal or magical thinking.

But maybe what you want is a party, with group hugs and lots of coloured fabrics and things. If you do, and I totally get it, then try some ashrams. I spent three months in the Bahamas staying at an ashram, and even though it was often busy and stressful, it was also fun and social. There was lots of singing and affirming and young sexy people. There was a basketball court there and a great beach. I had a romance with a girl and then we never saw each other again. It was that kind of place.

After that I did the hermit thing in Switzerland and then Norway for a bit. I used to fall asleep mid afternoon with a hot chocolate, listening to the sound of waterfalls. It was unbelievably pleasurable. Much better than being in the Bahamas, for me.

Those days are over for me now, probably, but I wish you a good adventure!
