The spiritual counterpart of the cities of refuge is Torah. Just as at every crossroads there had to be a sign bearing the words “Refuge, Refuge,” so too, a person must become a living signpost.
Everything that exists in the physical world also exists in the spiritual realm. Indeed, the spiritual dimension is the source and primary reality from which the physical matter derives. This is illustrated by the account in which the Rebbe Rashab explained that the Mitteler Rebbe knew about a nerve in the brain that assists the faculty of memory—something that was discovered only during the lifetime of the Rebbe Rashab—because the Mitteler Rebbe perceived this matter at its source in the Supernal Man.
The spiritual meaning of the cities of refuge is Torah. Just as at every crossroads there had to be a sign bearing the words “Refuge, Refuge,” so too, in spiritual life a person requires help and assistance, and needs Hashem to help him in his Divine service.
A person merits Hashem’s assistance when he himself helps others who are standing at a crossroads and shows his fellow Jews the path of “You shall choose life.”
A person must become a living signpost. This follows the conduct of the Baal Shem Tov and his disciples, who traveled to Jewish cities and settlements rather than waiting for Jews to come to them. Similarly, my revered father-in-law, the Rebbe, entrusted his students with the mission of becoming living signposts that show others the road to the refuge of Torah.
Even when a person thinks that he has accomplished nothing, his own assessment is not decisive. We find a similar concept regarding the removal of chametz: even when a person searches and does not find any chametz, he has nevertheless fulfilled the mitzvah of removing chametz.
Moreover, in truth he does have an effect. When another Jew sees him, that Jew may be awakened and reminded of his father, who taught him Modeh Ani, Shema Yisrael, and similar matters. Therefore, he should feel a broken heart because he did not merit seeing an inward and evident effect, but it cannot be said that he accomplished nothing.
There is a story of a “Conservative rabbi” who brought a Chassid before his students so that they could see that Chassidim still existed in America. This encounter led the children to begin asking their parents questions, and so on.
