The Poskim write that a person who is capable of analyzing Torah and acquire knowledge, but instead uses his time to recite Tehillim and Zohar or the like—is considered as having wasted Torah time. It goes without saying and it is all the more so if he actually wasted his time on empty endeavors, how much greater will his punishment be than for someone who does not have his abilities. And certainly one who has a scholar available to teach him Torah cannot exempt himself in his Day of Judgment with the argument that he did not know any better, because he was expected to go to that scholar who could have taught him. And we have learned in the Mishnah: “Who is wise? He who learns from any man.” And even if one did not learn Torah in his youth can still learn Torah in his old age. One who walks together with the wise becomes wiser tool. Conversely, one who does have much knowledge, should not withhold his bounty from others and he should share his knowledge with the people who seek Hashem. Let him teach even if he is not asked to do so and be accessible even when he not sought out. And when he is talking privately to individuals, let him endeavor to turn the conversation to words of Mussar and to tell them the correct path upon which they aught to walk and the deeds which they aught to do. Fortunate is the man who has found wisdom and the man who shares that wisdom with others. Behold! His reward is very great, for he thereby brings great satisfaction to his Maker, as elaborated in the Zohar.
