8. During the Aseres Yemei Teshuvah — Ten Days of Repentence — many have the custom of adding Chapter 130 of Tehilim (“Shir Hama’alos”) after “Yishtabach.” If one who has this custom finds himself in a location where this is not inserted, he should nevertheless follow his custom and say it quietly so that others do not notice it. Similarly, if one’s custom is not to say this chapter and he finds himself in a place that does, he should discreetly not say it.
9. During the Aseres Yemei Teshuvah people are more strict than the rest of the year and eat only baked goods produced with a Jew involved in the baking process (pas Yisrael), even though during the rest of the year they eat any kosher baked goods (pas paltar). If while traveling during the Aseres Yemei Teshuvah it is not possible to obtain pas Yisrael, then they do not have to be more strict than the rest of the year. Likewise, a person who generally is strict throughout the year but who will eat pas paltar on trips where pas Yisrael is not available does not have to be more strict during the Aseres Yemei Teshuvah under similar circumstances.
