We feel depleted by the constant demands from our lives. Our attention is outward, on people, places and projects. It drains our energy and we need to sleep to recover and regenerate.
Sleep in an involuntary turning inward, and eventually fails to refresh our energy. Meditation is simply turning inward by choice. It is available in small windows of time during the day and with a little practice become an effective tool to regulate our energy and emotions so that we can recover from specific outward drains on our energy and equilibrium.
It is worth learning because you get more of yourself back that just relying on sleep alone. With practice, people and events drain you less. You grow a more cohesive sense of self. You increase your capacity to be present, and that changes everything.
