The Alter Rebbe studied with the Magid for several weeks, but he felt that he had not found himself; that the Magid of Mezrich was not the right Rebbe for him. As was the custom at the time, the Alter Rebbe visited the Magid to bid him farewell and seek a blessing for his journey home. During the visit, the Magid accepted his decision, but told him that he should also say goodbye to “the Malach, the angel,” i.e., the Magid’s son Reb Avraham who was known as the Malach because of his great holiness.
The Alter Rebbe agreed and bid farewell to the Malach, who would later become the Alter Rebbe’s chevrusa. He offered to walk the Alter Rebbe to his horse, wagon, and driver. Before the Alter Rebbe got onto the wagon, the Malach said, “When you get into the wagon, you will see that the driver will smack the horse and it will begin running in an attempt to distance itself from the smack. And then the driver will smack the horse again, and it will run even faster, trying to escape the one pain of the whip. And it will continue on this way throughout your journey. But an intelligent person is not a horse. When an intelligent person feels a smack, he does not simply run away from it. He looks back to see who is smacking him and why he is being smacked.”
Being a deep and contemplative person, the Alter Rebbe understood the Malach’s message and stayed in Mezrich, ultimately becoming one of the star students of the Magid. May we all merit to understand the message of the wagon (עגלה) and look beyond the suffering of the world of strict justice to see G-d’s loving kindness, and thus merit the final redemption, quickly (בעגלא) in our days.
