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...
