On one occasion, the Elder Chortkover said, “When a tzaddik ‘says toire’ (Hasidic sermon), he must mekasher (spiritually bind) himself with his generation to be metaken (spiritually repair) them. However, if we are so distant that we do not attain a hitkashrut (spiritual binding) with the generation, then we should not need to say toire.” After that point, he stopped saying toire.
