Native American Indian rain 'ceremony'

I heard about a native American Indian chief who was invited to a rain dance ceremony in California some years ago. They were desperately in need of rain and hundreds of people gathered in a circle to watch. This humble man walked into the centre of the circle and stood there with eyes closed for one minute then walked away. Many people were puzzled, some disappointed and angry. What kind of ceremony consists of standing still with eyes closed for 1 minute and then it's over?
