Reb Yoel Kahan related:
There was a certain yeshiva that didn’t allow the bochurim to have any relationship with Chassidus, but their thirst could not be quenched. They would gather in one room in the dormitory, where one rebellious bochur owned a radio, borrow the device from him, and tune into Reb Yossel Weinberg’s weekly Tanya shiur.
One day, that rebellious bochur was also present, and he overheard Reb Yossel repeating a message from the Rebbe’s Pesach Sheini farbrengen, that had transpired a few weeks prior, that s’iz nito kein farfalener, no one is ever lost. This bochur was very moved by the message, and it had a profound impact on him.
When Reb Yossel heard of this, he reported it to the Rebbe. He added, that since a few weeks already passed from Pesach Sheini, he had considered not sharing the sicha, but had in the end decided to say it.
“Indeed,” the Rebbe responded, referring to Reb Yossel’s last point. “This is the entire message of Pesach Sheni, that it is never too late!”
