A Jewish person may increase and honor his internal aspect – that is, the Israel part of himself – above the external aspect, the aspect of the other nations. He may focus his efforts and energies on increasing and raising his internal aspect for the betterment of his soul, and he may minimize his efforts to maintain the “other nations” aspect within himself, his bodily needs. That is what the mishna in Avot states: “Make your Torah fixed and your work temporary.” [If he does so,] his actions cause the inner, “Israel” aspect of the world to rise and ascend, while the external, “other nations” aspect of the world will recognize and respect the value of Israel.
