"Anyone who has had an experience of mystery knows that there is a dimension of the universe that is not that which is available to his senses. There is a pertinent saying in one of the Upanishads: When before the beauty of a sunset or of a mountain you pause and exclaim, ‘Ah,’ you are participating in divinity. Such a moment of participation involves a realization of the wonder and sheer beauty of existence. People living in the world of nature experience such moments every day. They live in the recognition of something there that is much greater than the human dimension."
