Chasidut zu Mischlej 4:7

For the time being we will provide you with a brief answer. Shlomo HaMelech made it known in his ruach hakodesh⁴²Divine inspiration. (Mishlei 4:7), “The acquiring of wisdom is the beginning of wisdom.” The Torah is like a hammer that smashes down on hot iron⁴³The author actually said, “like a hammer that shatters rock,” but begging his forgiveness in Gan Eden, I changed it to hot iron to enhance the imagery. and sends sparks flying to all places in man, even in the finest cracks and crevices, bringing light to the darkest of places. From the plain meaning of this verse we learn that it is impossible for a man to use wisdom if he has not acquired wisdom, made it his own and is indeed wise to begin with. With this in mind, we similarly find that if you manage to enter a measure of wisdom into a boor, seeing as the wisdom is not his and he has no wisdom to begin with, then therefore even thought you have managed to give him this one piece of wisdom, still he cannot use it, analyze it, or understand any other wisdom by himself. Only if he were to truly become wise, then he could use this wisdom, and discern that which he wants to know at every moment and in every matter.
