The first and last articles connect to the initial chapter of Pirkei Avot ("Major Sayings of the Sages"), which we study on the six afternoons between the festivals of Pesach and Shavuot.
Articles 2-3 continue with our Kabbalah and Chassidic insights for the 49 days of Counting the Omer.
This week's Torah reading, Acharei Mot, is the subject of articles 4-6.
