A Collection of Laws, “the Breastplate of Judgment,” The Laws of the Guarantor, Law 3-30: The main thing about observing the Torah is the desire and it is attained by unity. Therefore, everyone should be incorporated in the community of Israel in great unity. And therefore during the receiving of the Torah, they must immediately become responsible for one another. It is because when they want to receive the Torah, they should immediately be incorporated as one, in order to be incorporated in the desire, then everyone is certainly responsible for his friend since they are considered one.”
What is unity, what is mutual guarantee?
It is a state in which I “is replaced” by every member in the group; I receive his reward and punishment, and everything that belongs to him. It is as if you have done whatever he has done. You deserve whatever he deserves. There are no investigations and no examinations; I am fully responsible. This is called connection or ultimate incorporation.
Of course, we don’t reach that immediately but step by step. On the whole, the general vessel must return to its whole state. Now the ego separates us, all the parts of this vessel, and we have to reconnect into something that is totally homogeneous and unified. In order to do that we “absorb,” cover the borders between us with love, go outside and connect between us, as if the borders do not exist. Thus we increase the intensity of the connection between us by 620 times, which is the sum of 613 commandments of the Torah and seven more commandments of our sages. Thus we are incorporated into one desire by mutual guarantee.
