Be the witness of your thoughts. Each day offers an enlightening quote, koan, sutra, or parable that reflects the spirit of Zen. The Zen of Friedrich Nietzsche: One must still have chaos in one, to give birth to a dancing star. The Zen of Osho: The real question is not whether life exists after death. The real question is whether you are alive before death. The Zen of Mother Teresa: Be happy in the moment, that's enough. Each moment is all we need.
