You can release the past by loving it.
What you have now would not be possible without those experiences. You cannot leave something until you love it. The more you hate something the more bound you are to it, and the more you love it the freer you are. So as you love the past, you are free from it.
Everything in your past happened for your good. If you could believe that the universe is friendly, that it is always helping you to create your highest good, you could live a life of more peace and security.
If you wish to be aware of the higher good happening in your own life, be willing to let go of a limited perspective and enlarge your view of your life. In many ways your past acts as an anchor until you release and let go of any negative beliefs about it or memories of it. You can go back and change negative memories by looking at the gifts people had for you and seeing the good you did for them. You then can telepathically transmit forgiveness and love to those people at whatever age they were when you knew them. You will heal youself and others by doing this. The healing will occur in present time also, and erase any projection of negative patterns into your future.

(...) as far as your life situation is concerned, there may be things to be attained or acquired. that's the world of form, of gain or loss. Yet on a deeper level you are already complete, and when you realize that, there is a playful, joyous energy behind what you do. being free of phychological time, you no longer pursue your goals with grim determination, driven by fear, anger, discontent, or the need to become someone. nor will you remain inactive through fear of failure, which to the ego is loss of self. when your deeper sense of self is derived from being, when you are free of "becoming" as a psychological need, neither your happiness nor your sense of self depends on the outcome, and so there is freedom from fear. you don't seek permanency where it cannot be found: in the world of form, of gain and loss, birth and death. you don't demand that situations, conditions, places or people should make you happy, and then suffer when they don't live up to your expectations.everything is honored, but nothing matters. forms are born and die, yet you are aware of the eternal underneath the forms. you know that "nothing real can be threatened".when this is your state of being, how can you not succeed? you have succeeded already. -eckhart tolle
