When working on corrections we have to work in the opposite direction of the shattering and to understand that everything depends on our mutual incorporation. Therefore, the correction begins from having an inclination, a deficiency, a need, to unite for different reasons.
There is a purely pragmatic aspiration to unite in order to make a living from one another in the corporeal sense, and there is the commandment to connect in order to earn from one another spiritual advancement.
All the corrections are performed by mutual incorporation. So when we want to put the shattered vessel together again, we should make sure that a person feels that he is an inseparable part of the world. That is, he has to correct the whole world in order to correct himself.
This means that a person will not be able to correct himself unless he corrects his connection with the whole world, with all of humanity. Although it may seem impossible, we depend on one another in the correction to the same extent that we depend on one another in the shattering.
To the extent that I depended on everyone during the shattering, as is being revealed now, I also depend on everyone during the correction. So even if I only perform minor personal corrections that I manage to carry out, I thus touch every person in the world. It is because we are in an integral system in which there are no detached parts, but where everything is connected and everyone influences one another.
Of course, everyone operates according to his level and according to his Reshimot (spiritual genes), according to the depth of their fall during the shattering and after the sin of the Tree of Knowledge. But still, if we pull a certain thin wire at the end of the system, the whole system rocks and moves, and is accordingly invoked either for better or for worse.
That’s why it is said: “He who saves one soul of Israel, it’s as if he saved the entire world.” It’s because he who is called Israel (according to his yearning for the revelation of the Creator, the force of bestowal and love in the desires) corrects his attitude to the system he encounters at least to the first level of Nefesh, and by that he certainly influences the whole system.
For this reason it is said in The Book of Zohar that when Israel corrects themselves, the Upper Light that comes into their vessels pours outside and fills the whole world. This means that we don’t have to take care of the world, but it is enough to take care of those who can wake up. Although we can go out to the public and hasten their development.
