This Sicha focuses primarily on the third Raia from Arai Miklat (Halacha 2) and explains the need for this third proof (and in a second Halacha) because it links Moshiach to a Mitzvah which must be literal and physical and impossible to change. He explains that the three proofs have three ideas each with their own unique strengths: 1) Torah, 2) Nevua, 3) Mitzvah.
