“People act in accordance with their beliefs, and skeptics are no different. Hence it is reasonable to expect that a skeptic will feel free to use as a basis for action any ideas that are shown to meet his criteria of legitimacy. On this basis, there is not only one, but several proofs for the existence of G-d and, as mentioned, there is no problem if one is forced to say that this existence is not grasped by the senses or the mind, or even if it contradicts rationality. As long as this existence accounts for observed reality and does so better than any other proposition, we have what is usually considered to be conclusive, scientific proof.”

“The gates of editing are never closed.”

The same is true of the teachings of Chabad Chassidism. It reveals the essence of our souls, the highest of our potentials. The Alter Rebbe’s contribution enables this potential to influence and affect the functioning of all our powers, and thus be expressed in every aspect of our lives.
