Walden is a Rhapsody to Mindfulness

 

 I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.

 Henry David Thoreau, Walden (1854)
US Transcendentalist author (1817 - 1862)
