A walk in nature can help bring about one of the most essential acts a human being can perform: the stilling of the mind. For when the cacophony of disturbances, reactions, and self-talk subsides, like a windswept sea suddenly finding calm, the lens of our lives becomes a still, pure crystalline window for the cosmos to experience itself through... A walk in the natural world, with conscious mindfulness, can help bathe the senses in the implicate ordering of existence. Such a direct and immediate reminder does much to help steer us back to the center of ourselves.
And, from Mother Teresa:
God is the friend of silence. We need to find God
But we cannot find God in noise, in excitement.
See how nature, the trees, the flowers, the grass
Grow in deep silence ... the stars, the moon and the sun
Move in silence ...
The fruit of silence is prayer. The fruit of prayer
Is faith. The fruit of faith is love.
The fruit of love is service ...
(The fruit of service is peace.)
