How can we sharpen awareness of thoughts that gush forth in the mind like Niagara Falls? Observe them gently, not clinging and with diligent focus. Our present moment awareness and unstoppable attention, when sustained inwardly, have the transformative power of a Niagara to cleanse the heart of all impurities. Therein is the path to freedom. A talk given during an Ottawa Buddhist Society retreat at the Sisters of St. Joseph Convent, Pembroke, Ontario, Canada, 2009.
