…the Now, the most precious thing there is. Why is it the most precious thing? Firstly, because it is the only thing. It’s all there is. The eternal present is the space within which your whole life unfolds, the one factor that remains constant. Life is now. There was never a time when your life was not now, nor will there ever be. Secondly, the Now is the only point that can take you beyond the limited confines in your mind. It is your only point of access into the timeless and formless realm of Being.
From the book called, “Power of Now: A Guide to Spiritual Enlightenment” by Eckhart Tolle.
