We must be open to the Tao, to the Holy Spirit, to our Higher Power, if we are to have any peace. Wind stirs the water and it becomes muddy and full of debris. When the water becomes calm, it settles and becomes clear. We need to settle and become receptive to our awareness of the transcendent instead of roiled and distracted by the turbulence in the external world.
In the spiritual life, we are aware of our need to be receptive, to simplify, to turn inward and shut off the distractions of daily life. Peace, equanimity, serenity comes from listening to the whispers of God not from business and strife created by competition and rushing from one source of stimulation to another. In Psalm 46:10 it says, "Be still, and know that I am God."
