Hearing can be a source of even more exquisite pleasure but it requires conscious cultivation. I have had people tell me they had never heard the song of a wood thrush, although I knew the bell-like phrases of this bird had been ringing in their back yard every spring. By suggestion and example, I believe children can be helped to hear the many voice about them. Take time to listen and talk about the voice of the earth and what they mean - the majestic voice of thunder, the winds, the sound of surf or flowing streams.
