The essence of milk is butter, the essence of the flower is honey, the essence of grapes is wine, and the essence of life is wisdom. Wisdom is not necessarily a knowledge of names and forms; wisdom is the sum total of that knowledge which one gains both from within and without. An intellectual person will argue, will dispute, but very often about a subject which he himself does not know fully; and frequently one finds that he does so for the very reason that he does not know the subject fully. Superficially the argument of such people makes one believe that they know it, but for the very reason that they argue it is evident that they do not. The one who knows does not need to argue; he knows; and he is so satisfied with this knowledge that he does not have that hunger which is felt by the person who argues.
