“Amen” (אמן – gematria = 91) – When saying amen one is often “Yotze” (צא – gematria = 91) with the bracha.
חמש backwards spells שמח. When one learns the five books of the Torah he receives happiness in return.
“טבעא, however is one” (Kiddushin 5a – explaining that Kesef Kiddushin can’t effectuate a divorce and marriage because a coin is established through one mint and they all retain likeness, thus voiding it to used for divorce, as the prosecutor cannot also be the defendant).
The “shoresh” of טבעא is טבע (nature). When it comes to money, all of man is made out of one mint with the unending attachment to money.
שלם (complete) = ש”ע (acronym for Shulchan Aruch). One can be deemed complete when he knows all of the Shulchan Aruch, which is the final compilation of Halacha for all of “Torah shebaal peh.”
מחשבה (thought) and שנה (year) both equal 355 (additionally שנה equals 355 days, a possible number of days in the Hebrew calendar). One’s mind should be in constant thought of Torah all year.
A family member of the Steipler always found it difficult to get to speak to the Steipler for he was always learning. Once, as the Steipler was peeling an item of food for his wife, the family member thought he found an opportune time. He went over to the Steipler whereas the Steipler replied, he has no time for he’s in the middle of a sugya (Divrei Siach – Parasha Korach).
Rav Avrohom zt”l held as well that one has an obligation to learn while doing chesed.
There was a case that took pace on the 15th of Shevat, where a son asked his mother if there were any dates in the house (for they take precedence in regards to the “Shivat Haminim”). The mother replied that there were none so the child made a bracha on other fruits. When he was ready to make the “bracha achrona” the mother remembered that she did have dates. Does the son now have to make to new “borei pri ha’eitz” on the dates?
Rav Avrohom Zt”l said that it seems the son would not have to make a new bracha based on the “Head of Household” principle, and even though in this case the Baal Habayit didn’t think there were any dates, it is assumed that when a person makes a bracha, they rely on everything the ball habayit will tell them, even though at the time of the bracha the baal habayit said there were no dates.
Rav Avrohom Zt”l then brings a proof to this Halacha from “Afikomen” on Pesach.
However, Rav Avraham zt”l asks on the case of dates, how we can say that the first bracha on the fruit will cover the dates, for this would go against the law of “kadima” in brachos for the dates are more “chasuv” than regular fruits and the Rashba holds in such a scenario this can’t be done.
However, unlike the Rashba, we hold the “Head of Household” principle is effective in this case as brought down by the Biur Halacha (Siman 211 Sief 5.)
