Maariv

• We say Oseh HaShalom at the end of the Amidah as well at the end of Kadish. This is continued during the Ten Days of Repentance.
• After the Amidah, we recite Vayechulu, and the mini repetition of the Amidah as is usually recited on Friday night. (The word “HaMelech” replaces the word “HaKeil.”)
• We also recite Psalm 24 (LeDavid Mizmor). Saying this prayer with concentration is a segulah (spiritually propitious act) for parnassah (ample livelihood) throughout the year. One may also recite this prayer at home anytime during this night.

Prayers

• During these judgment days, one should take care to recite every word of prayer clearly and not garble them.
• According to the Arizal, when one is moved to tears during the prayers on the High Holidays, it is a sign that he is being judged at that time. Therefore, one should pray with great kavana (concentration) at that time. If one doesn't cry at all during these days, it is a sign that one's neshama (soul) is blemished.
• Even if one was, G-d forbid, sealed for death in the book of the wicked, he can fix this and be written in the book of life for the tzadikim by doing teshuvah and praying with tears.
• See below regarding the laws of the special insertions in the prayers during the Ten Days of Repentance.
