I think that I cannot preserve my health and spirits, unless I spend four hours a day at least — and it is commonly more than that — sauntering through the woods and over the hills and fields, absolutely free from all worldly engagements. – Henry David Thoreau
The mark of solitude is silence, as speech is the mark of community. Silence and speech have the same inner correspondence and difference as do solitude and community. One does not exist without the other. Right speech comes out of silence, and right silence comes out of speech. – Dietrich Bonhoeffer
