Experience has confirmed to me what the Rebbe / Kabbalah teaches – We are a perception of ourselves – but similar, to Einstein’s statement, "reality is a perception, albeit, a very persistent one!" – the world outside of us, is also but a perception! (this has been confirmed by both, the quantum physics – You can’t make this up! rather it comes from scientific experiments! – that a. atoms are literally popping in and out of existence (in other words, you and the entire universe) continuously b. how you look at them effects their state!) and the goal of all these awesomely "permanent" perceptions is: to learn how to be humble
