Falling and Flying

There is a famous photograph of construction workers on the Rockefeller Centre in New York sitting in a row along a narrow girder, hundreds of metres above the street, having a relaxing lunch break without the security of safety harnesses, ropes or handrails. Even looking at these photos unnerves many people, because we humans generally have an instinctive fear of being pulled to our deaths by the force of gravity. How do these forces work?

Why does attentiveness to nature matter? In a very fundamental sense, we are what we pay attention to. Paying heed to beauty, grace, and everyday miracles promotes a sense of possibility and coherence that runs deeper and truer than the often illusory commercial, social "realities" advanced by mainstream contemporary culture. ... Our attention is precious, and what we choose to focus it on has enormous consequences. What we choose to look at, and to listen to--these choices change the world. As Thich Nhat Hanh has pointed out, we become the bad television programs that we watch. A society that expends its energies tracking the latest doings of the celebrity couple is fundamentally distinct from one that watches for the first arriving spring migrant birds, or takes a weekend to check out insects in a mountain stream, or looks inside flowers to admire the marvelous ingenuities involved in pollination. The former tends to drag culture down to its lowest commonalities; the latter can lift us up in a sense of unity with all life.
