What Hiskashrus Means

Once, a yungerman approached Rav Aharon of Czernobyl and expressed his wish to become miskasher, to attach himself to the Tzaddik in the bond of chossid and Rebbe.

When Rav Aharon heard this, he turned to the chossid and said, "You want to be tied to me? Let me explain to you what hiskashrus means. When Moshiach comes, the Rebbe will need to tie a big, fat gartel around his waist (chassidim wear the gartel during tefilla and when appearing before someone, as a sign of respect). The Rebbe will be first in line in the procession to greet Moshiach, and whoever is mekushar, tied or bound to the Rebbe, will have to hold on tight to the gartel and approach, walking together with him."
