Krias Shema Al Hamitah
When saying Krias Shema Al Hamitah, say Baruch shem etc. out loud. Omit the paragraphs omitted on Shabbos and Yom Tov.
Before going to sleep, say kapitlach 124–132 of Tehillim.
When arising in the morning, wash negel vasser until the knuckles.
When saying birchos hashachar, omit the berachah of She’asah li kol tzarki.
From the age of nine or ten (depending on ability), children should be educated to delay their meals.
There are sources that state that the fast of Yom Kippur should last for 26 hours. However, the Rebbe writes that one can fast a little over 25 hours, and those few minutes are considered as a complete hour.
Shacharis
When saying Shema (during korbanos and Shacharis), say Baruch shem etc. out loud.
In the early years, the Rebbe would stand whenever the aron kodesh was opened. However, in later years, the Rebbe would remain seated.
Similarly, there were years when the Rebbe would stand at the conclusion of the berachos during chazaras hashatz, and there were years when the Rebbe would remain seated.
Krias Hatorah
When the aron kodesh is opened, say Vayehi Binsoa Ha’aron, the Yud-Gimmel Midos Harachamim (three times), the Ribono Shel Olam for the Yamim Nora’im, and Berich Shemei.
For krias hatorah, two Sifrei Torah are removed from the aron kodesh. From the first Sefer Torah, five aliyos are read in Parshas Acharei (Vayikra 16:1–34). The second Sefer Torah is then placed next to the first one, and Chatzi Kaddish is recited. This is followed by hagbah and gelilah of the first Sefer Torah.
With the exception of Maftir, the Torah is read with the special tune of the Yamim Nora’im.
From the second Sefer Torah, Maftir is read (Bamidbar 29:7–11). This is followed by hagbah and gelilah of the second Sefer Torah, after which the haftorah is read (Yeshayahu 57:14–58:14).
Yizkor and Musaf
Krias hatorah is followed by Yizkor. Those whose parents are alive leave the shul during Yizkor. During the first year of mourning, the mourner stays in shul but does not recite Yizkor.
During Musaf, if the floor of the shul is made of marble or stone, put down a towel or other separation before bowing during Aleinu and Vehakohanim.
The Kohanim duchen during chazaras hashatz. Before duchening, the Kohanim wash their hands as usual (until the wrist).
Musaf is followed by the Tehillim of the day, as well as kapitlach 133–141. Additionally, say the Sheish Zechiros. Do not say Ein Keilokeinu and Aleinu.
We make sure to take a break (for at least 45 minutes, if possible) between Musaf and Minchah.
