A dilemma posed to R. Nachman: when one swears off property, does that make the use of that property its own violation, as per me'ilah, the violation of property consecrated to the Beit HaMikdash? Also, the new mishnah: what is included and excluded when one swears off benefit from another person? What can the limited person still do for or with the other? For example, the role of a kohen that goes beyond personal benefit... When can he function in his official role, even for one who has sworn off benefitting from him, and when can he not?
