This aspect of “Great Love of Hashem” comes from Above, corresponding to the “מִּש ְּקָּל-measure” of each person, according to his own measure of doing good Mitzvos and turning away from bad sins,
This service from the person must be complete before he can receive the corresponding love from Above.
The reason this type of love it is called, “ש ֶׁקֶׁל-Shekel,” is because it only comes to the person according to the “מִּש ְקָּל-measure” of how much he refines himself in the performance of the Torah and Mitzvos.
The Shekel coin, which represents this love, is also called in Parshas Chayei Sara “עו ַׁבֵרַׁל ס ַׁו ַׁחֵר-it passes around as currency everywhere.” This word ‘סּ ו חֵר-currency’ is related to the word ‘סְחו ר-encompassing’ or surrounding, as in the phrase (Shabbos 113a) “A Nazir should go ‘סְּחו רַׁסְּחו ר-all the way around’ a vineyard so that he shouldn’t come to eat grapes.” This is a reference to a level of Divine Revelation that “encompasses all worlds.”
In the story of how Avraham our forefather bought the burial plot for Sarah (which was the Mearas Hamachpala), the Torah says that Avraham spent 400 Shekel HaKodesh, which were "עובר לסוחר". The simple meaning is עובר-passes לסוחר-as currency, which means that it was a very valuable coin that was acceptable currency in all places, because of its globally recognized value. Here, we are translating the words as follows: עובר-passes לסוחר- around in an encompassing manner. The word לסוחר, which means “for business,” or “as currency used in business,” is related to the word סחור , which is Aramaic and means “to go around or encompass” and it means that the love that comes from Above (which is called 'Shekel,' like in the story of Avraham and in our verse,) comes from a level of Divine Revelation which encompasses all the worlds. This level is called "encompasses all worlds" not because it is not present within the worlds, but because it is so unlimited and transcendent that we are unable to perceive it, and thus it remains "above" and "encompassing" our understanding.
This love, which is a gift from Above, is an expression of this higher truth that “encompasses all worlds.”
The Alter Rebbe will bring proof to show that this love is from the level of Divine Revelation that "encompasses all worlds:"
This lofty level of love is the idea of the “400 silver Shekels” used to buy the Mearas HaMachpaila, which is connected to the level of “the 400 Worlds of Yearning that we will experience in the World to Come.”
In the story of Avraham buying the land, he used 400 silver Shekel coins. It is explained in Kabbala that these correspond to the "400 Worlds of Yearning" that will be revealed in the World to Come. This shows that this type of love is, indeed, from a very high level, since it is connected to "Worlds of Yearning," meaning an intense love, that is so great that it cannot be (fully) revealed until the World to Come, since it so intense that the world now is not able to receive it.
