When we work to balance our awareness on the breath, eventually it falls off. Maybe after one breath, two breaths, or even half a breath. The usual rivers of the mind (neuro-pathways or sanskaras) are powerful. Imagine the Grand Canyon and the Colorado river. All of the rain drops in the area (energy) effortlessly flow to join that river in the pathway that has been carved through time. Our rivers of focus might be anger, frustration, doubt, worry, distraction, analysis - and you might see the ways that subtle thoughts wick through to join a large familiar river that could easily sweep you away.
