How do you make lasting change in the world? According to Bhante Saranapala, a Buddhist Monk at the West End Buddhist Temple and Meditation Centre in Mississsauga, Ontario, it starts with one person's kindful acts toward another. And they pass it on. On a sunny fall day in Serena Gundy Park in north Toronto, he talks to Steve Paikin about his early life training to be a monk in Bhangledesh and Sri Lanka, his time in Canada, leading meditation sessions for police and other professionals, and spreading his message of mindful kindness, the topic of his book, "Are You Kindful?: How your practice of kindfulness can build a happy and peaceful nation."
