The greatest sgula is what Hashem told us at Sinai: ואתם תהיו לי סגולה מכל העמים - You should be a special nation for me from among all the nations.
R' Aviner
Since people today are searching day and night for Segulot, inventing new ones and paying a fortune for them, we decided to collect all of the proven Segulot which we have heard from our Rabbis:
Segulah for Shalom Bayit
A husband should help his wife or, more precisely, the two of them should take care of the family's needs together since theirs is a shared life.
Satmar Chasidim end Shabbat very late due to a long Seudat Shelishit and the Rebbe's talk. Once, on a Saturday night, the Satmar Rebbe saw that one of his Chasidim was the last one in the Beit Midrash and was folding his Talit with great precision. The Rebbe asked him what he was doing. The Chasid said that he saw in various books that care in folding one's Talit is a Segulah for Shalom Bayit. The Rebbe responded: A better Segulah is to go home and help your wife wash dishes (And others say this incident in the name of Ha-Rav Chaim Shmulevitz, Rosh Yeshivat Mir. The book "U-Piryo Matok - Bereshit" of Ha-Rav Yitzchak Zilberstein, p. 140).
Segulah for the Education of One's Children
A good education, since for education, one has to work and invest.
Ha-Rav Chaim Kanievski related that someone once came to Ha-Griz Soloveitchik – the Brisker Rav – and asked for a blessing that his son should be a Torah scholar and G-d-fearing. The Rav said that he will be a Torah scholar based on how much you learn with him, and he will be G-d-fearing based on how many tears his mother sheds during Davening for him (Minchat Todah p. 89).
Segulah for Learning Torah
Learn consistently and without interruption.
Ha-Rav Herschel Schachter relates that after he was married, he and his wife did not have children, and they therefore decided to visit Eretz Yisrael. He was told that it is worthwhile to receive a blessing from the Steipler Gaon. The way it worked was that one bought a book from him and at the same time asked for a blessing. The Steipler was hard of hearing, and one would therefore communicate with him by writing on a notepad. The Steipler yelled in Yiddish: What can I do for you? Rav Schachter wrote that he wants to buy Kehilat Yaakov on Kiddushin, the Massechet they were then learning in Yeshiva. He bought it, received the change and said that the Steipler could keep the change as a donation. The Steipler said that he did not need the money, business is business. Then Rav Schachter asked for a blessing for children, and he blessed him. The Steipler asked: What else can I do for you? Rav Schachter said that he was learning in Kolel, and is it possible to receive a blessing for success in learning? The Steipler said: All the blessings in the world will not help. Rather sit and learn and you will succeed.
Segulah for Debts
If someone has debts, he should spend less than he earns and not rely on the miracle of overcoming the rules of mathematics.
The Tur wrote that one should limit his expenses. And the Mishnah Berurah wrote that this is a harsh criticism against those who are enticed to spend money on luxuries without seeing the consequences, which in the end will lead to theft and disgrace (Biur Halachah chap. 529). One should plan well.
Segulah for a Long Life
Honor your father and mother in order that you should have long life.
“Who is the man that desires life and loves days of seeing good? Let him guard his tongue from evil and his lips from speaking evil.” Tehillim 34:13- 14.
Segulah against Traffic Accidents
Driving carefully and performing kindnesses to those who need a ride.
And the Belzer Rebbe – Ha-Rav Aharon Rokeach – also gave the Segulah that if one follows the traffic laws with the strictures of the 10 Commandments, and also gives rides to those who need them, in the merit of these kindnesses which he does on the road, he will be saved from any bad occurrence (Shut Shevet Ha-Kehati 5:241).
All of these pieces of advice can be found in Ha-Rav Chaim Kanievsky's answer to the question: How do we know which Segulot are true? - "I only know that which is written in the Shulchan Aruch" (Segulot Raboteinu p. 321). And the Belzer Rebbe said that there is no greater Segulah than "Yirat Hashem" (Fear of Hashem), as it says (Devarim 28:58): "If you do not observe all of the words of the law, which are written in this book, to fear this Glorious and Awesome Name of Hashem, your G-d" (Shut Az Nedbaru 1:79 #179. Beit Baruch 1, 405. Brought in Shalmei Yehudah chap. 10 note #41
