Baal HaSulam, “The Arvut (Mutual Guarantee)” (an abridged version): Rabbi Elazar said that the whole world is included in mutual guarantee, but first, only Israel (those who have an aspiration for it) begins the correction of the world… (while others, due to a big ego) do not agree to exit self-love.
The first ones who are willing to be corrected are those who, besides egoism and usual troubles of this world, also have a special calling, spark that beckons forward. They take the direction straight to the Creator (Yashar-El) and therefore are called “Israel.”
The 99% of humanity develop only under the pressure of suffering from behind. This circle is called the “nations of the world.” And there is also an inner circle, which besides suffering, also has an aspiration to move forward. These people are called “Israel.” Of course, those who have both the pressure from behind and are also pulled forward come to the realization of mutual guarantee sooner. However, the entire world will have to enter the framework of mutual guarantee eventually.
The “nations of the world” also have parts that will connect with “Israel,” by suddenly discovering a spiritual calling or the point in the heart. But others will not enter inside. So one way or the other, the central group must correct itself, becoming a home for those who are attached to it and who support it from outside.
The conclusion is simple: It is our duty to realize correction. Everything is entrusted to us: to correct ourselves and the world. There is nothing to add.
