Disseminating the Wellsprings of Chassidus to the Outside World
The Baal Shem Tov writes in a letter (Reproduced in Keser Shem Tov [Kehos NY 1981 p3) that on Rosh HaShonoh of the year 5507 (1746) his soul ascended to the heavenly realms, where he was granted the privilege of entering the palace of Moshiach. He writes as follows: I asked the King Moshiach, “Master, when are you coming?” And he replied: “When your wellsprings will be disseminated outward.” (Mishlei 5:16 The metaphor of “wellsprings” signifies “teachings”.)
On this exchange the Rebbe Rayatz commented: “From this reply it is apparent that the teachings of the Baal Shem Tov - the revelation of the Divine Intellect which the Baal Shem Tov and his disciples and their disciples (our forefathers, the Rebbeim) bequeathed us - are very closely connected with the coming of Moshiach. ... Moshiach is an Ohr Atzmi, quintessential light itself, and the teachings of Chassidus are the vessel for this great light.” (Likkutei Dibburim Vol.2 p269/273/4).
Outwards
The Previous Rebbe translated Chassidus into other languages in a manner which corresponds to the non-Jews’ level of understanding. Hence, his efforts can be described by the expression “spread the wellsprings of Chassidus outward.” He took the “wellsprings” of Chassidus, the deepest mystical secrets of Torah and had them translated and thoroughly explained in the seventy languages of the world. Thus, we can see various different levels in the service of “spreading the wellsprings of Chassidus outward.”
In general, this service began in the time of the Baal Shem Tov, more particularly it began in the Alter Rebbe’s generation, and specifically after his arrest and release from prison. We see yet another stage of “spreading the wellsprings of Chassidus outward” which began in the generation of the Rebbe Rashab. However, the generation of the Previous Rebbe, the seventh generation, of which it is said “all seventh are dear” began a new stage in which the “wellsprings” reached outward, to a point where they are comprehensible even to those who (for the time being) are removed from the Jewish way of life, in the languages and context of their understanding.
The above produces a practical lesson. ... we must add more strength and effort to spread (not only Nigleh, but also) “the wellsprings of Chassidus outward.” We must reach out to a Jew who is at the moment separate from his Jewish roots and immerse him in the wellsprings. We must speak to him in his language and in a manner that he, too, can understand. Thus, we will prepare for the Messianic redemption. In this generation, all the good deeds of the previous generations are collected, thus producing a great treasure of good deeds. Therefore, we will merit the fulfilment of the prophecy “as in the days of your exodus from Egypt I will show you wonders,” with the coming of Moshiach.
