At first silence had seemed a deprivation, a symbol of an unwanted isolation. I had resented the solitude of my life and fought it. But gradually the enveloping quiet became a positive element, almost a presence...It seemed to hum, gently but melodiously, and to orchestrate the ideas that I was contending with, until they started to sing too, to vibrate, and reveal an unexpected resonance. After a time I found that I could almost listen to the silence, which had a dimension all of its own. I discovered that I felt at home and alive in the silence: it had become my teacher.
Einstein told us that our universe is shaped and defined by light. We live in a visual cage, and what we call time is simply the ever-moving shadow of the bars which confine us....But suppose that...we were able to outrun the waves of light which undulate across the universe. As we leap...across the galaxy we overtake and leave behind the light which left the surface of the earth...the image will travel forever in this everlasting night, seeking its home among the stars, reaching ever outward toward some hypothetical destination at the universe's problematic end. Is light, then, the stuff our souls are made of?
