"And Elohim went up from him"
Here Rabbi Shimon discusses Jacob's unique and privileged position as revealed by the title quotation. Because Jacob encompasses all the Patriarchs, he is a Holy Chariot to Zeir Anpin by himself. Indeed, his perfection was completed by the name 'Israel,' which the Shechinah bestowed upon him. We learn of the great good fortune of the children of Yisrael, who alone among nations have God to receive their prayers and petitions.
A reading of this section helps elevate us to experience some of the perfection embodied by the Patriarchs, inspiring us to follow the path of righteousness and summon down more Light.
