To be identified with your mind is to be trapped in time: the compulsion to live almost exclusively through memory and anticipation.
This creates an endless preoccupation with past and future and an unwillingness to honor and acknowledge the present moment and allow it to be.
The compulsion arises because the past gives you an identity and the future holds the promise of salvation, of fulfillment in whatever form.
Both are illusions.
Eckhart Tolle, The Power of Now
