The Rebbe was the greatest master ever, the master of all Masters, as it says, Moshiach will teach Torah to the forefathers, and even Moshe Rabeinu!, as I heard from Rabbi Kesselman who heard from Rabbi Hirshprung who was from the greatest Torah scholars who knew the greatest Torah scholars of the previous-generation, "None begin to compare to the Rebbe…" without going into too many accolades, for those who understand scholarship, understand already… so everything the Rebbe teaches us, boils down to following…: number one: Don’t be an idiot – number two: Don’t be cruel – number three: God knows what He’s talking about, so don’t be dumb and ignore – number four: because life is about growth, and life is infinite, it means your life is about infinite growth!! and last but not least: each and every one of us, is always obligated to fulfill our purpose of existence, which is a continuous duty, which can only be done in a state of Joy, Love, and Happiness
