Did you know we all have "set points"? Points during past, present, or future lives in which something significant happened?
I was recently reminded of this during a new meditation I was trying, in which an alternate "version" of me brings me a gift of knowledge. This "other self" had an awareness that I am currently seeking, and the gift was to bring that awareness in to my present-self consciousness.
This probably sounds odd to some, but makes perfect sense to me. Time is a man-made construct, so any concept of "now" and "then" is just our perception.
My studies and my experience have taught me that any time something amazingly wonderful, or alternatively, traumatic, happens a set-point is created, rather like a re-set point on your computer.
As well, other "mes" have understandings, knowledge, experience that you either do not yet have or have forgotten.
I find this topic fascinating, and have had some amazing experiences playing with those other Hollys. If it is a topic you wish to explore, seek out the best resource for you, whether a YouTube video, mentor or teacher, or healer, and give it a try. Release judgment and accept the gifts!
