Talking about being Moiser nefesh,
I was in Mir Yeshiva one year rosh hashana, and Reb Nosson Tzvi shlita came to the overflow minyan (850 people!) to speak. Those that know him are aware that he suffers badly from severe parkinsons desease. Anyway he was brought into nevat (the hall where the minyan took place, but he was too weak to walk. He was literally dragged in. He was so weak he couldnt stand up to speak. He sat down, and we waited to see what would happen, half expecting him to be taken home. I watched in amazment as he pulled himself together, stood up and leaning on two shtenders gave a short divrei chizuk, begging everyone to take upon themselves to be moiser nefesh for torah and mitzvos.
I turned to the person sitting next to me and “Ehr ken redden”. (He is the right person to give such a talk) He knows what it means in its full sense to be moiser nefesh for torah and mitzvos!!
I hope you all join me in wishing him much Koach and gezunt to continue his avoidas hakoidesh for many more years!
