Spiritual Amnesia

Not long ago I came across a article that ended up discussing an issue I had trouble with before, but never gave much thought to.  The article shed some light on a process that occurs very frequently with me, and up until reading it, I couldn't understand why my perception of things would change so drastically overnight.  The article (linked below) talks about talks about the spiritual mentor of the author, performing levitation for his audience, only for that memory of said demonstration to change by the next day.
