 Buddhism holds that this very same striving is at the very root of human unhappiness.The Buddhist concept and practice of mindfulness meditation has been adopted by psychologists such as Rick Hanson ("Buddha's brain", 2009), T.B.Kashdan & J. Ciarrochi ("Mindfulness, acceptance, and positive psychology", 2013) and Itai Ivtzan ("Mindfulness in Positive Psychology", 2016).
