It is a small gathering in central Yokohama one Sunday morning in early August. Around 20 people are sitting in an unusually relaxed position, listening to quiet meditative music.

Chinese businessman Ben Inn -- leader of the Bruno Groening Circle of Friends in Hong Kong -- then stands and addresses the assembly. He visits Japan at least once a year because his wife is Japanese and she and their twin daughters like to see family in Kawagoe.

"I'm not the kind of person who is interested in aggressively trying to help Bruno's groups to develop," he begins. "However, I am happy to share my story with others -- people like yourselves who might benefit from the kind of help I received. That's the reason why I'm speaking to you during my family vacation."
