The past, present and future are all connected. Things that happened in the past can come back to bite us when we least expect it. Worrying about the future can keep us from living in the present. When we heal we have to consider that whatever we're working on exists in all time, in all dimensions, and in all space. When we shift our energy we shift all energy because, guess what, we're part of EVERYTHING! All time and all space exist in the here and now and within each of us.
When we heal something in the present it connects back to our past and also into the future. We have the ability to heal back in time to the beginning of an issue and in doing so we change the variables that created the present moment which in turn transforms our future. How cool is that?!
When we shift a defective energy pattern into a healthy energy pattern we shift our entire health and well-being because, of course, everything is connected.
