The once-every-five-years Australian Census is upon us (Census night is August 9, 2011). Which means the vexed 'What is your religion?' question will raise its head.

"I thought I'd potter off around the world and try to find people who sincerely and unsarcastically synchronise spirituality with popular culture. Is it good, is it trivialising, is it even spiritually dangerous?"
