Unease, anxiety, tension, stress, worry—all forms of fear—are caused by too much future, and not enough presence. Guilt, regret, resentment, grievances, sadness, bitterness, and all forms of nonforgiveness are caused by too much past, and not enough presence. Most people find it difficult to believe that a state of consciousness totally free of all negativity is possible. And yet this is the liberated state to which all spiritual teachings point. It is the promise of salvation, not in an illusory future but right here and now.
— Eckhart Tolle
