Jun Po (pronounced June Poe) Denis Kelly Roshi is the 83rd Patriarch of Rinzai Zen, having received inka from Eido Shimano Roshi in 1992 at the age of 50. Jun Po has been teaching Zen ever since that time and has built an international community called Mondo Zen that spans the United States, Canada, Europe, and Australia. His extraordinary life was detailed in the biography A Heart Blown Open (Divine Arts Media, 2012), which has just been used as the basis of a screenplay.

Keith Martin-Smith is the author of three additional books, including the award-winning A Heart Blown Open. In addition to writing, he also teaches Shaolin Kung Fu and is an ordained Zen priest.
