As long as you are unable to access the power of the Now, every emotional pain that you experience leaves behind a residue of pain that lives on in you.
Eckhart TolleIf you have a strong ego [and] something good happens to an acquaintance of yours, [it] makes you feel bad. It's called envy. ... The ego thinks something has been taken away from you because somebody else has received something good. It's a complete illusion, but that's the madness of the ego.
Eckhart TolleAll 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.
