1,345. Davening During Shiva

210:3 Even if the mourner is a kohein and there is no other kohein in shul, he may not be called for an aliyah.

210:4 During the week of shiva, the mourner does not recite Pitom HaKetores or Maamodos. In Eizeh Mekoman, he does not say the Yehi Ratzons. This section asks G-d to consider the prayers as if we had brought the actual sacrifices, and a mourner does not offer sacrifices. When reciting havdalah over a cup after Shabbos, a mourner does not recite the verses of joy at the beginning; he just starts from the brachos.
