3994 - Message from the Rebbe to the annual dinner of the Central Lubavitch Yeshivah:

The Chanukah story teaches us that even in a holy place like the Temple, while outwardly it remains intact, it is possible to defile it. The only way to combat this is through self-sacrifice. The unique quality of the students of the Lubavitch Yeshivah is their mesiras nefesh, not just for themselves but also for others. https://www.torahrecordings.com/rebbe/igroskodesh/012/003/3994
