Step by step instructions on developing your practice by beginning with close attention to your breath. You can overcome the five obstacles to your practice by investigating the characteristics of wanting, aversion, sleepiness, restlessness, and doubt as they arise. With curiosity and determination return again and again to the breath. A deep purification occurs and the mind becomes concentrated leading in time to the deep spiritual maturity of a calm, still, spacious mind. A talk given during a Theravada Buddhist Community retreat in Toronto, 2007.
