The psychological condition of fear is divorced from any concrete and true immediate danger. It comes in many forms: unease, worry, anxiety, nervousness, tension, dread, phobia, and so on. This kind of psychological fear is always of something that might happen, not of something that is happening now.
Eckhart TolleWhen you look at a tree and perceive its stillness, you become still yourself. You connect with it at a very deep level. You feel a oneness with whatever you perceive in and through stillness.
Eckhart TolleAs you go about your life, don't give 100 percent of your attention to the external world and your mind. Keep some within.
