Nothing can change the past, including thought. However, dwelling on thoughts about the past does change our experience of the Now. When we drag the past into the present, everything else that belongs to the Now is marginalized and overlooked. All we see is the past or, more accurately, our story about it. All we can ever have of the past is our story about it, and that story is very unsatisfying. Our stories about the past don't feed our soul like the Now does. And worse, any story is usually a sad tale that keeps us caught up in negative feelings, and then those feelings become our current experience of life.
