The Previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn, wrote the following in a Chassidic discourse:
A person must have a penchant in loving his fellow. When a one meets his fellow, he asks him, “Brother, how are you?” This is a natural way of speaking amongst chassidim.
Even when he gives him a kiss and asks him, “Brother, how are you?” this is done by rote. Such is what his father, grandfather and great-grandfather did before him.
Yet this is love for your fellow which is “dry”—it lacks life. Love for your fellow must have a “moisture” which brings to a true connection between the parties…
This love must be present even when your fellow is not acting as he should. One must realize that this [that he is not acting properly] is up to you. Were he to know what you know, surely he would be a changed individual. Were you yourself to act properly, surely your fellow would learn from you.
(Sefer HaMaamorim, 5710, Pg. 264)
