In the Christian calendar,  this day is the last one of the liturgical year. With sunset this evening, Advent begins,  and the start of a new year.

With every breath, the old moment is lost, a new moment arrives. This is something meditators know. We breathe in and we breathe out.  In so doing we abide in the ever-changing moment. We learn to welcome and accept this entire process: we exhale, and we let go of the old moment. It is lost to us. In so doing, we let go of the person we used to be. We inhale and we breathe in the moment that is becoming: we repeat the process. This is meditation. This is renewal. It is also life
