Many erroneously see the Rebbe, in fact any or all of our great sages wisdom, as being their strongest feature – which is like seeing the flavor of a drink being its sum total; of course the essence of the drink and its true effect only comes from the fact that it is a water (imagine the flavors minus the water) similarly, the essence of the greatness, hence effectiveness of the Rebbes and all our great sages wisdom, is, because it was Godliness coming through them.
