סי' יז ויהי הם מריקים שקיהם

The Book Yerech HaAisonim — in it are explained many wondrous matters from the topic of the holiness of Rosh HaShanah and the sounding of the Shofar and the prayers of Rosh HaShanah, and the great merit of one who is privileged to be near a true Tzadik on Rosh HaShanah, and the topic of the custom that was practiced to go on Erev Rosh HaShanah to pray at the graves of the Tzadikim; and likewise explained within it are the topics of the holiness of the Ten Days of Repentance, Yom Kippur, Sukkos, Sh'mini Atzeres, and Simchas Torah, and the holiness of all the mitzvos of G-d which are observed during them.

The author defers entirely to Likutay Halachos, Laws of Lulav, Law 2, where it is explained how the topic of Rosh HaShanah, Shofar-sounding, Sukkos, and the Four Species all revolve around this discourse. He notes that although more could be explained, he chose to be brief here.
