Baal HaSulam, “The Arvut (Mutual Guarantee)” Item 17: The giving of the Torah had to be delayed until they came out of Egypt and became a nation of their own, so that all their needs were provided for by themselves, without dependence on others. This qualified them to receive the above Arvut, and then they were given the Torah.
The condition for the giving of the Torah, the method of correction, is readiness for mutual guarantee.
In general, the Torah is the Light that Reforms, which helps a person to the degree that he is ready to be a guarantor. In other words, the Torah works for a person if he is ready to unite with another, up to the point of loving the other.
If the person is not ready for this, the Torah doesn’t work for him, the Light is not shed. After all, the Light only comes as a reaction to a person’s effort to do something for another.
This principle resembles an electrical system with resistance (R). Depending on the amount of resistance between me and another, the Light that Reforms, the Surrounding Light (Ohr Makif –OM), will come.
So, the Light that Reforms also called the Torah influences us. And it acts upon us on the background of inner clarification discerned through the evil inclination, which is what provides the resistance.
