The Rebbe mirroring God (as it states, Tzaddikim mirror their creator) proves that infinite greatness, is not only, not egotistically related, rather, is directly related to infinite humility; in fact, Einstein himself says “I am embarrassed by all the attention paid to me, for discoveries that took no effort!” So, the wiser you are, the more you realize, how all of your wisdom is only a gift, not your ability!
