Presence is needed to become aware of the beauty, the majesty, the sacredness of nature. Have you ever gazed up into the infinity of space on a clear night, awestruck by the absolute stillness and inconceivable vastness of it? Have you listened, truly listened, to the sound of a mountain stream in the forest? Or to the song of a blackbird at dusk on a quiet summer evening? To become aware of such things, the mind needs to be still. You have to put down for a moment your personal baggage of problems, of past and future, as well as all your knowledge; otherwise, you will see but not see, hear but not hear. Your total presence is required.
