Recently I was asked if you could physically change the past with space/time magic. The person specifically brought up a technique I mentioned in Space/Time Magic, where you can influence your past self via a meditation technique in order to guide and influence that past self.
Throughout my life I’ve had moments where I’ve encountered a future version of myself that gave me advice or pushed me in a specific direction or warned me away from a direction I might have gone down. I know when I’ve followed that advice/push or pull in a specific direction its generally worked out in my favor, but it does create an intriguing question.
Was I interacting with my future self or with a version of my future self, or what?
