The power of positive thinking and Buddhist meditation techniques saved the life of a Chinese construction worker.
It was a cool early spring day in the eastern coastal port of Ningbo. Wang Jianxin was working at a construction site in the booming city. The job that day for the 52-year-old worker was to dig a five-metre ditch. There was nothing to distinguish Mr Wang from the tens of thousands of men across China labouring in one of the biggest building booms that the world has seen.
Without warning, a wall of the ditch collapsed, burying Mr Wang under a huge pile of earth. Like most construction workers in China, he had little in the way of protective equipment except for his tough plastic safety helmet. It was to be enough to save his life.
The rim of his helmet had, by chance, trapped a tiny pocket of air around his face. Mr Wang knew that if he panicked and his breathing accelerated he might use up that little amount of oxygen before rescuers could reach him. He forced himself to be calm.
