The Buddhist Teachings of Thích Nhất Hạnh
"Mindfulness is the core of Buddhist philosophy; Hanh defines it as 'the energy that brings us back to the present moment.' ... Buddhist philosophy suggests that true happiness comes from remaining focused on the things we do, and doing them with no purpose other than to do them."
