The Rambam, in Hilchot Talmud Torah (3:12), writes that one cannot achieve success in Torah learning if he learns in a relaxed manner, and only when learning is convenient and comfortable. Like anything else in life, a person excels only through persistence, diligence, and hard work. "Dabbling" in Torah will not result in Torah scholarship – just like "dabbling" in any other field will not lead to mastery or excellence in that field. There are no shortcuts to achievement in Torah study. Rav Mordechai Gifter (1915-2001), Rosh Yeshiva of the Telz Yeshiva in Cleveland, would say that a lot of students want to learn the entire Shas in one night – and also manage to sleep eight hours that night…and to learn while sipping soda… Quite obviously, this is not how it works. A person can succeed in Torah learning only if he is prepared to put in the time, work and effort, and to learn even when conditions are far less than ideal. This includes learning even when one feels tired. Although a person should certainly sleep as much as he needs, he should ensure to use the rest of his time for Torah learning, and not for sleeping beyond what he needs for his physical and emotional wellbeing. Many sources emphasize the particular importance and value of learning Torah during the nighttime hours. In fact, the Gemara (Erubin 65a) states explicitly that the nighttime period was designated specifically for Torah learning. And the Rambam writes in Hilchot Talmud Torah (3:13): "Even though it is a Misva to study both during the day and at night, it is only at night that a person acquires the majority of his wisdom. Therefore, whoever wishes to merit the "Crown of Torah" should be careful with all of his nights, not wasting even one of them on sleep, eating, drinking, idle chatter, or the like—rather, [spending them] in the study of Torah and words of wisdom." The Rambam concludes: "And any house in which the words of Torah are not heard at night will be consumed by fire." If one's "fire" – his passion, his excitement and energy – is directed somewhere else other than Torah, then his home runs the risk, Heaven forbid, of being consumed by fire. The Torah tells (Bereshit 28:11) that when Yaakob was leaving Eretz Yisrael, and he reached the site where the Bet Ha'mikdash would be built, he went to sleep ("Va'yalen Sham"). The Midrash comments that Yaakob slept there – but did not sleep at all during the fourteen previous years, which he spent learning Torah in the yeshiva of Shem and Eber. The commentators explain that this cannot mean that he literally remained awake for fourteen years. Rather, it means that during that period, Yaakob never actually went to sleep in a bed. When he needed to, he put his head down, or found a place to lie so he could get the small amount of sleep that he needed. In order to achieve in Torah learning, one must be prepared to sacrifice physical comfort, and to keep his sleep to a minimum. A different passage in the Midrash tells that King David would go to sleep at nightfall, but he kept a musical instrument by his bedroom window, that served as a kind of "alarm clock." At Hasot (midnight), the wind would blow the strings, producing music, and David would wake up to learn Torah. The Yeser Ha'ra (evil inclination) would try to convince him to go back to sleep, saying that kings normally enjoy the luxury of sleeping late, as they do not have to rise early for work like the commoners. But David would ignore the Yeser Ha'ra and spend the rest of the night engrossed in Torah study. The Gemara (Sukka 26b) instructs that if a person needs to sleep during the day, he should sleep for only a brief amount. Elsewhere (Erubin 65a), the Gemara relates that Rav Hisda's daughter asked why he slept so little, and he replied that soon – after his passing – he would have plenty of time for sleep… Our limited time here in this world should be used productively, and not wasted on excessive rest and relaxation. The Midrash Tanhuma (Parashat Noah, 3) warns that in order to succeed in learning the intricate material of the Torah She'be'al Peh, one cannot aspire to wealth and luxuries; the only way to excel in Torah learning is by sacrificing physical and material comforts. Similarly, Tana De'beh Eliyahu Zuta (14) warns that excessive eating and sleeping leads to "poverty" in the area of Torah knowledge. Normally, when a person stays up late at night and sleeps only the minimum that he requires, he is likely to appear the next day pale, drained, and bleary-eyed, and might not be very pleasant to look at. However, the Gemara (Hagiga 12a) promises that if a person spends his night learning Torah, Hashem "casts a cord of Hesed" over him. This means that he will have a certain "charm" the next day, earning people's admiration and favor despite his fatigue. In a different passage (Sanhedrin 71b), the Gemara teaches that when the righteous sleep, they and the entire world suffer a loss. As the Sadikim spend their time productively, involved in meaningful pursuits that benefit them and the entire world, they and the world lose as a result of the time they spend sleeping. (Conversely, then, when the wicked sleep – and thus are not engaged in their sinful behavior – they and the entire world benefit from their inactivity.) The Gemara in Masechet Menahot (110a) teaches that scholars who spend their nights learning Torah are considered as though they offer sacrifices in the Bet Ha'mikdash. And in Masechet Tamid (32b), the Gemara states that if a person learns Torah at night, the Shechina accompanies him wherever he goes. The Talmud Yerushalmi (Ta'anit 3a) cites Rav Ada Bar Ahaba as avowing that he never slept an entire night, as he always rose early to learn Torah. The Reshit Hochma ( Rabbi Eliyahu de Vidas, 1518–1587) writes that when one learns Torah at night, he is not seen; his study is private, without publicity and fanfare, and this lends it a very special quality. Since he learns secretly, he is worthy of having the hidden secrets of the Torah revealed to him. An especially stern passage appears in Abot De'Rabbi Natan (29:3), warning that if a person is awake at night and not involved in Torah learning, "he would be better off had he been strangled at birth." Rabbenu Yona (Spain, 1200-1263) writes that if a person stays awake at night learning Torah, then he obviates the need for Yisurin (punishments). Since he subjects himself to the discomfort of remaining awake to learn Torah, this counts for whichever kinds of suffering he needs to experience. This is alluded to by the verse in Tehillim (94:12), "Ashreh Ha'geber Asher Teyaserenu Y-ah U'mi'Toratecha Telamedenu" – "Fortunate is the man whom G-d punished, and teaches him from his Torah." This can be read to mean that a person is fortunate if he receives his punishments by immersing himself in intensive Torah learning, exerting hard work and effort. Rabbenu Yona further notes that Moshe Rabbenu did not sleep at all throughout the forty days he spent atop Mount Sinai receiving the Torah – setting an example of minimizing sleep for the sake of Torah learning. If, Rabbenu Yona adds, a king invited someone to his treasury to collect as many riches as he could for a specific period of time, this man would certainly not sleep at all during that time, and would use every moment he could to collect riches. We, too, should use as much of our limited time in this world as we can for Torah learning, collecting spiritual "riches," rather than waste our time indulging in physical comforts. Rav Besalel Ashkenazi (Israel, 1520-1592) writes that in his youth, he spent his nights engaged in Torah study, often learning throughout the night without sleeping. He also occasionally skipped meals. It was through this sacrifice of physical comforts for Torah learning that he achieved Torah scholarship. The Reshit Hochma writes that his esteemed mentor, Rav Yosef Taychik (1465-1546), did not sleep in a bed for forty years, and would instead sit on an elevated piece of furniture with his legs dangling, such that he would not stay asleep for an extended period. He rose every night at midnight and spent the rest of the night learning Torah. And a disciple of Rav Yehonatan Eibshutz (1694-1764) testified that throughout the years he spent learning under him, Rav Yehonatan never slept in a bed, and instead dozed for brief periods in his chair. Rav Chaim Brim (Jerusalem, 1922-2002) related that the Hazon Ish (Rav Abraham Yeshaya Karelitz, 1878-1953) was once found sleeping on his bed in the wrong position – with his feet on the side where the head was supposed to be. The people told him to turn around, and he said, "If I had the strength to turn myself around, I would learn another Tosafot." The Hazon Ish continued learning Torah until he had no strength left, not even to turn his body around. Rav Haim Palachi (Turkey, 1788-1868) wrote that if a person could see into the future, to the time when he would be in the grave, and understand the extent of the regret he would experience for not having used his time properly, he would never waste time, and he would minimize his sleep in order to spend more time learning Torah. Rav Palachi added that a person who rises at midnight to learn Torah earns the status of a "friend" of Hashem and of the Nation of Israel, and he will be spared punishments that befall the rest of the world. The Reshit Hochma notes that when rising at midnight to learn Torah, one should be driven solely by his genuine love for Hashem, and not by any ulterior motives. Only if his intentions are pure will he reap the precious rewards for learning Torah at night. The Reshit Hochma says that as a teenager, he devoted himself entirely to Torah study, engaging in virtually no other activities. The Peleh Yoetz (Rav Eliezer Papo, 1785-1828) urges us to train ourselves to sleep fewer hours and to learn Torah even when we feel drowsy, in order to maximize the amount of time
