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.
To pray is to pay attention to something or someone other than oneself. Whenever we so concentrate our attention that we completely forget our own ego and desires, we are praying.
