Musar על ביצה 31:24

Therefore, I exhort you to train yourself to sit as much as possible, because the sin of the tongue is the most severe, as our Sages said (Tosefta Pe'ah 1): "These are the things...and lashon hara is equivalent to them all." I don't have to elaborate on this most serious sin of all. "All man's toil is for his mouth" (Koheles 6:7). Our Sages said that all man's mitzvos and teachings are not enough to counterbalance what comes out of his mouth. "What should be a man's pursuit in this world? He should be silent" (Chullin 89a). One must seal his lips as tight as two millstones. Idle words are like powerful weapons which can reach from one end of the world to the other. Now, this is true concerning mere excessive speech. Where forbidden speech is concerned - e.g. lashon hara, mocking, swearing, vowing, fighting and cursing - especially in the synagogue, and on Shabbos and Yom Tov - for every utterance of this type it is impossible to imagine the pain and suffering one will receive (Zohar)! No word is lost; everything is recorded. Winged beings attach themselves to everyone, recording all they say. "For a bird of the skies may carry the sound, and some winged creature may tell the matter" (Koheles 10:20). "Let not your mouth cause your flesh to sin, and do not tell the messenger that it was an error. Why should G-d be angered by your speech and destroy the work of your hands?" (ibid. 5:5). Purchase all your needs through a messenger, even if this would cost two or three times as much. "Is there a limit to what G-d can provide?" (Bamidbar 11:23). Hashem feeds all creatures, from the greatest to the smallest (see A.Z. 3), and provides all their needs. And on Shabbos and Yom Tov do not speak at all about things that are not urgent, and be brief even with what is important, for the Shabbos is very holy and our Sages barely permitted the exchange of greetings on it (Yerushalmi Shabbos, and Tosfos Shab. 113). See how strict they were concerning even a single expression! Continue to give great honor to the Shabbos as when I was there. Do not cut back [on your Shabbos] expenses, since "Man's entire sustenance [for the year is fixed for him from Rosh Hashana to Yom Kippur,] except [the expenditure for Sabbaths and Festivals,] etc." (Beitzah 16a).

Raise your own children as well correctly and sensitively, and pay their tutor well, for "Man's entire sustenance for the year is fixed for him from Rosh Hashanah...except TiShReY (Talmud, Shabbos, Rosh Chodesh and Yom Tov - Beitzah 16a). I have also left books for them. For Hashem's sake, guide them well and gently. Take care of their health and make sure that they always have enough to eat. First have them learn the entire Chumash, seeing to it that they know it almost by heart. The learning must be done without undue pressure, rather gently, because it is best absorbed when one is relaxed. Give them coins, etc., as a reward.

And I know their excuses, that the times are difficult, etc. But, in truth, if they searched their souls they would know that the yetzer is only deceiving them. For in other things, which are only of physical benefit to their son, does not each one of them assist his son with all of his strength, even more than he is able? And sometimes, he even places his life in danger because of him, doing things which are against the din, both between man and his neighbor and between man and the L-rd. And he blesses himself in his heart, saying: "All will be well with me, for I am doing charity at all times by feeding my family." But when he must support his son in Torah, to know how to serve the L-rd, bringing both his son and himself to eternal life, as we shall adduce below from the midrashim of Chazal, he says that times are hard! And this is as Scripture states (Isaiah 93:2): "And not Me did you call upon, Jacob; for you grew weary with Me, O Israel" — "with Me," specifically. As we find on this verse in the Midrash, Esther Rabbah 3: "All day he is busy working and does not become weary; he prays, and he becomes weary!" And, in truth, the expenditures for the Torah study of his sons are outside of the expenditures for sustenance fixed for him on Rosh Hashanah, as Chazal have said (Beitzah 16a): "All the sustenance for man is fixed for him from Rosh Hashanah until Yom Kippur, except expenditures for Shabbath, …and expenditures for his sons' Torah studies, which, if he gives less, he is given less [by Heaven], and if he gives more, he is given more." Come and see what Chazal have said (Kiddushin 30a): "If one teaches his son's son Torah, Scripture reckons it unto him as if he had received it on Mount Sinai, viz. Devarim 4:9: 'And you shall impart them [(words of Torah)] to your sons and to the sons of your sons," followed by (Ibid. 10): 'the day you stood before the L-rd your G-d in Chorev.'" Also, through this, he merits long life for him and his sons, it being written (Ibid. 11:19): "And you shall teach them to your sons," followed by (Ibid. 21): "So that your days be prolonged and the days of your sons, etc."

The common denominator of the concepts of שבת and משכן are that they both are symbols of עולם הבא, the World to Come. There is a baffling story in the Talmud Beytzah 16 describing that Shammai bought and ate only food intended to honour the Sabbath. Should he find a good looking animal, he would purchase it intending to eat it on the Sabbath. Should he find a superior one later, he would abandon the first one and eat it during the week so as to preserve the better one for serving on the Sabbath. The Talmud contrasts Shammai's conduct with that of his colleague Hillel whose every action is described as being לשם שמים, "Heaven oriented." Are we to infer from this that Shammai's actions were not "Heaven oriented?" What then was the difference of opinion between Hillel and Shammai which caused them to have different approaches to their daily routines? They disagreed on whether it was permissible to serve G–d in order to accumulate rewards payable in the World to Come. (This is elaborated on in Midrash Shemuel Avot 1,3.) Shammai considered serving G–d for material rewards in this world as forbidden, whereas he considered serving G–d in order to accumulate reward in the Hereafter as perfectly permissible. His colleague Hillel considered serving G–d in order to receive a reward either in this world or in the next as equally forbidden. This is what the Talmud means when describing Hillel's actions as "Heaven oriented," i.e. without thought of any reward.

However, that which can protect a person and save him from these detriments is trust in G-d. Namely, that a person casts his burden entirely upon G-d, knowing that it is certainly impossible for a man to lack what was designated for him, as our sages taught: "all of a person's sustenance [for the year] is fixed for him from Rosh Hashana [to Yom Kippur]" (Beitzah 16a). Likewise, they said: "no man can touch what was prepared for his fellow even to the extent of a hair's breadth" (Yomah 38b).
