We must abandon completely the notion of blaming the past for any kind of situation we're in and reverse our thinking and see that the past always flows back from the present. That now is the creative point of life. So you see it's like the idea of forgiving somebody, you change the meaning of the past by doing that...Also, watch the flow of music. The melody as its expressed is changed by notes that come later. Just as the meaning of a sentence...you wait till later to find out what the sentence means...The present is always changing the past.
