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, which settled comfortably and caressingly around me like a soft shawl. 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. Silence itself had become my teacher.
