|A story of the Rebbe #201 - "From the Walls of 770"|
Rabbi Meir Harlig relates that at one time a particular bochur who did not study or behave appropriately stayed in the yeshiva in 770. After a while, he left 770 and got engaged. Before his wedding, he wanted to go back to 770 for several weeks, but the administration of the yeshiva refused to accept him.
When the bochur heard this, he wrote to the Rebbe that he wanted to be in 770 for a while before his wedding. The Rebbe approached the yeshiva's administration and told them that while he understood their decision they should allow the bochur to be there because, "from the walls of 770, one can receive many things."
