18a. Vayedaber Elokim 5714, Class One. כל המצוות של האבות ריחות היו אבל אנו שמן תורק שמיך כמריק מכלי אל כלי What the Avos lack that we have. Our Neshama and Guf (body) joins through Gevura to join the opposites of the highest Neshama and the lowest body. This Gevurah is then used to overcome the challenges of this life and correct the world and bring Aliya to the Neshama. The idea of Gevura is thoroughly developed. To bring from the highest of the high to the lowest of the low you must skip steps. From the highest Ayin to the Yesh.
