"And he saw that rest was good... and he bowed his shoulder to bear" (Genesis 49:15)

Through the Torah, you activate all the cells that have already been damaged, weakened, and have begun to wither. The learning renews them, activates them, gives them intellect. The Torah builds you and makes you a new person.

Issachar is the only neshamah (soul) among all the tribes that had no connection to this world! Issachar is the neshamah that has nothing in the world except for Torah study. It is the neshamah that everyone must serve. Each tribe does something: Zebulun engages in commerce "Rejoice, Zebulun, in your going out," Judah wages wars, Levi serves in the Holy Temple, but Issachar is the neshamah that has nothing in this world... only Torah study! Issachar is only Torah, because Torah study is greater than the service in the Holy Temple as it is written "She is more precious than pearls" (Proverbs 3:15), greater than the High Priest who enters the innermost sanctum.

A mamzer who is a Torah scholar is greater than a High Priest who is an ignoramus. If he studies Torah day and night, he is greater than a High Priest, because one cannot escape the evil inclination except through diligent Torah study. This is specifically when a person toils himself, to the point of death, to the point where he wants to die "A man who dies in a tent," one must toil in Torah, to give one's life for it, not to study Torah out of laziness, out of comfort. Complete Torah study is not out of comfort! A person has all kinds of desires, and he also has a desire for comfort. All desires are hinted at in the chiefs of Esau, and one of them is "Chief Comfort." A person loves to go in comfort, to be in comfort, to study in comfort, but the true comfort, the true rest, is only the Torah "And he saw that rest was good... and he bowed his shoulder to bear" – the yoke of Torah (Rashi). True rest is the rest of the soul – through Torah study, the soul is polished, cleansed, all the filth is scraped off, all the filth is thrown out, and one merits the rest of the soul.

A person must know that he is responsible for the acts of creation, every day he must create the world anew, the world is conducted according to those who study Torah, through Torah study the world is created. "For all the renewals of the acts of creation that Hashem renews every day continuously, that on this day there is much rain and on this day there is dryness, and at this time it is cold and damp, etc., and similar changes – all through the Torah... " (Likutei Halachot, Yibum 3) Rabbi Natan explains that you create the world, if you were negligent in study and slept, a disaster occurred, you dreamed and spoke with someone during study, a disaster occurred. A person must know there is no need to read newspapers or know what is happening in the world, you only take an interest for one second in the world, a disaster happens. A person must believe that the moment he is idle from Torah, a disaster occurs! You must know that all changes in the world go according to your Torah study, when a Jew studies, then the whole world begins to love us, because all the nations sometimes love us and sometimes hate us, those who studied history know that one year they love, one year they hate and want to annihilate all the Jews, because everything depends on our Torah study, not on politicians or anything else.

When a person studies Torah diligently, and he puts his mind into the Torah, he creates new worlds! He creates a new reality! Suddenly, he has new laws! He has money to travel to Uman! And suddenly he has abundance in spirituality, abundance in materiality! Because he created a new world, before he was in a world where he had no money, and now he is in a world where he already has money! Because a completely new world has already been created, because every moment a person creates new worlds, if a person studies Torah diligently, then he creates new worlds every second. The Rebbe brings in Torah 101 "And when a person commits a sin, God forbid, then the sin and the iniquity are engraved on his bones, as it is written (Ezekiel 32): 'And their iniquities shall be upon their bones.'" The Rebbe says you want to atone for your sins? You want to erase your sins? It's difficult! After all, your sins are engraved on your bones, the sins have made the bones broken, all the bones of the person are broken, it hurts here, it hurts there, it's all from the sins, every sin and sin makes an engraving on the bone, "And their iniquities shall be upon their bones," the bones are hollow, they are already engraved, they are broken from the many engravings. If a person wants to reconnect the bones, to rebuild them, to escape from "their iniquities upon their bones," it is only through diligent study, to take exams, to study Torah diligently, because for a defect, teshuvah (repentance) does not help because the bones are already broken, already engraved, so what is the relevance of teshuvah? – Now you need to continue new intellect into the bone, to renew the bone, and this is through diligent Torah study, through the Torah you activate all the cells that have already been damaged, weakened, and have begun to wither. The learning renews them, activates them, gives them intellect, the Torah builds you and makes you a new person.

A person seeks advice on how to escape bad traits, so he has Hitbodedut and Chatzot, and everything is wonderful and good, but if he does not have diligent Torah study, nothing will help him, because if a person does not study Torah diligently, then the main thing is missing from the book, then there is no intellect at all, because the intellect is only received from diligent Torah study. If a person does Hitbodedut but has no intellect at all, then Hashem wants to give him, but there is nowhere to continue the abundance! A person prays with intention, and after the prayer, he already runs to eat, he runs to talk with his friend, they say "Aleinu" he already removes the tefillin, he is already talking with his friend, so Hashem says to him I want to give you after the prayer, just say a verse, say 2 or 3 halachot, study a few lines from the Gemara, then you will have wonderful intellect and understand everything, because after the prayer a person asks "And give in our hearts understanding to understand and to comprehend to listen to learn and to teach to keep and to do," and Hashem wants to give him now all the intellect, but he immediately begins to talk with his friend, and here he runs before Aleinu, and he already removes the tefillin, and he is already outside, he is already talking, and already arguing, and already eating, and Hashem says I wanted to give you wonderful intellect where did you run away from me? – – –

So the Rebbe says that without diligent Torah study there is no intellect, and in everything a person does the main thing is missing, because the main thing the Rebbe says is diligent Torah study, and therefore the Rebbe brings in the "Sefer Hamidot" (Learning section 33) "The habit of study surpasses the fulfillment of all mitzvot" one must get used to study, therefore we ask immediately in the morning "And accustom us to Your Torah" that we get used to Torah study, and the Rebbe says that getting used to it is not enough! So the person will say Gemara like Psalms it is not enough, it needs "And accustom us!" Studying diligently is called "And accustom us!" Take Rashba, and Ramban, and Ritva, and Shita Mekubetzet, and the Rosh, and the Rif, and the Ran, and the Nimukei Yosef, everything there is, and the Maharam Shif, and the Maharsha, and the Bach, and everything possible, and if the Maharsha is difficult for you take an easier commentator, but this is how your head must always be in diligent study, always standing in diligent study.

If a person studies diligently, "who delves into and understands the wisdom of the Torah, then he merits that the yoke of government and the yoke of worldly matters are removed from him" and this is only through diligent study, delving into and understanding the wisdom of the Torah, and then he merits radiant countenance, and then when a person's entire thought is only in diligent Torah study, to understand the Gemara well, to understand the sugya well, to understand all the Rishonim, and all the Acharonim, and to summarize it, and to write it, and meanwhile to innovate a few more innovations, then at that moment he merits such radiant countenance that the whole world returns in teshuvah, he receives such radiant countenance that the whole world returns in teshuvah from his face, – the wisdom of a person illuminates his face, "and thereby the yoke of government and the yoke of worldly matters are removed from him," and then there is no yoke of government in the world, no Russians, no Arabs, no non-Jews, nothing, no yoke of government, for one person who puts his head into diligent Torah study, Hashem is willing to remove the yoke of government from the world, all the yokes of governments, to nullify the governments so that only Israel will rule, only the Torah will rule.
