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.
