The basic human tendency is to repeat over again and again the same past experiences unconsciously. By exploring our own past lives we become aware of these repetitive, unconscious patterns and we erase our past by resolving those patterns. Only then, are we free from our past and the whole past is dropped.
Future progression is going forward in time, and experiencing the future events. It is only the probable future we see during this progression. We become aware of whatever blue print or life design we carry from inter-life states during this process. Future progression gives a direction, clarity of mind and even some healing.
We are creators of our own reality and we can always shape or re-frame or re-program or re-design our own lives.
