All negativity is caused by an accumulation of psychological time and denial of the present. 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.
Eckhart TolleDiscontent, blaming, complaining, self-pity cannot serve as a foundation for a good future, no matter how much effort you make.
Eckhart TolleIs there a difference between happiness and inner peace? Yes. Happiness depends on conditions being perceived as positive; inner peace does not.
Eckhart TolleThe mind, conditioned as it is by the past, always seeks to re-create what it knows and is familiar with. Even if it is painful, at least it is familiar. The mind always adheres to the known. The unknown is dangerous because it has no control over it. That's why the mind dislikes and ignores the present moment.
Eckhart Tolle
