The days of shivah and the yahrtzeit (Jewish
anniversary of passing) are especially vital times for the departed
soul. While any Torah study brings merit to the departed's soul, classic
Jewish sources cite specific customs which are said to be
particularly propitious for these days. These customs are discussed in detail in The Neshamah Should Have an Aliyah, pp. 58-63 and 130-132.
See p. 152 of The Neshamah Should Have an Aliyah for a list of Mishnayos perakim (chapters) for each letter of the Alef-Beis.
See pp. 153-164 of The Neshamah Should Have an Aliyah for individual Mishnayos, one for each letter of the Alef-Beis.
