What am I absolutely beyond a shadow of a doubt certain? – God is everything, everything else is both perceptions of everything else, as well as perceptions of itself (but as Einstein said, “reality is an illusion/perception, albeit a very persistent one.”) God created this perception, as He is loving, hence this perception a. creates us; b. gives us freedom of choice; but ultimately, freedom of choice is, as the Rebbe explains, not random, rather a sequence, in which the soul eventually discovers, it is in darkness, seeks light and then the light source, God-Himself begins to descend intimately, in a continuously ying and yang (rotzu-vshuv) fashion, giving us ever higher paradigms, which create ever greater growths and we will all live happily ever after!
