Why Chanukah Is the 25th Day | Reb Tzadok HaKohen on “כה” and Shema (Audio)

Chanukah is called “Chanu Kaf-Hei”—but what does that really mean, and why is the 25th day the turning point? In this audio shiur, Rabbi Yaacov Haber learns a powerful piece from Pri Tzadik (based on Tikkunei Zohar) explaining the difference between 24 and 25: the 24 letters of “Baruch Shem Kevod…” (Yichuda Tata’ah) and the 25 letters of Shema (Yichud Elyon)—and why you can’t skip the process and jump straight to “Echad.” Along the way, we connect this to “Ko amar Hashem,” Yaakov and the Shevatim, Rabbi Akiva being ma’arich b’echad, Noach and “chein,” and the search for the Ohr HaGanuz that Chanukah reveals. This is an audio-only shiur.
