Answer: The term mutual guarantee (“Arvut” in Hebrew) originates from the word “Learvev” (to mix). That is, mutual guarantee is such a mixture of opposite properties that they are indistinguishable from each other. In other words, people who want to be connected, and finding completely opposite qualities in themselves, interconnect with each other, “enter” each other: I am in him, and he is in me, and we exactly fit each other.
Everything in nature is created in this way. For example, a bee that sits on a wild flower is built exactly according to its form so that it can enter the flower without damaging it, gather all the pollen, and carry it to another plant. Everything is created precisely. Only Nature, the Creator, could invent in this way.
We are made in the same way: Male and female parts enter each other and interact ideally, unite, and complement each other.
Mutual guarantee is such mutual care, it is when I make a commitment to be everything for you, and you do so for me, that is, everything for everyone, because this mutual contact is necessary for each of us. By understanding and recognizing this movement towards each other, we thus enter into mutual guarantee.
