I did not know that prayers carve wood!
70 year-old Buddhist monk Hua Chi has been praying in the same spot at his temple in Tongren, China for over 20 years. His footprints, which are up to 1.2 inches deep in some areas, are the result of performing his prayers up to 3000 times a day.
The words and wording are unimportant. What is important is the dedication this man has to his religion. We can all learn from him especially us Christians!
