"Mystical experience of nature can be of particular relevance to our troubled age, bringing deeper into our consciousness and emotions the logic that nature sustains humanity as humanity must, in turn, sustain nature. Rationality alone, however, cannot be our guide in the task of restoring our environment. A spiritual connection to nature must inspire the emotional commitment that is the yin, complementing the yang of intellectual understanding."
