Principles of Spiritual Work in the Group
He who thinks that he is deceiving his friend, is really deceiving the Creator, since besides man there is only the Creator. This is because it is the essence of creation that man is called “creature” only with respect to himself. The Creator wants man to feel that he is a separated reality from Him; but except for that, it is all “the whole earth is full of His glory.”
Hence, when lying to one’s friend, one is lying to the Creator; and when saddening one’s friend, one is saddening the Creator.
