Peace can be threatening because peace is the absence of problems and conflict. There is something, perhaps in the personal you, that does not want freedom or peace, or the absence of problems. There's something that wants the opposite.
Eckhart TolleWhatever the ego seeks and gets attached to are substitutes for the Being that it cannot feel.
Eckhart TolleSo give your complete attention to what you feel, and refrain from mentally labeling it. As you go into the feeling, be intensely alert. At first, it may seem like a dark and terrifying place, and when the urge to turn away from it comes, observe it but donโt act on it. Keep putting your attention on the pain, keep feeling the grief, the fear, the dread, the loneliness, whatever it is. Stay alert, stay present - present with your whole Being, with every cell of your body. As you do so, you are bringing a light into this darkness. This is the flame of your consciousness.
