It is well known that there was a big split between Kotzker Chasidus and Ishbitzer Chasidus. One Chossid once returned to Kotzk after spending some time in Ishbitz.
When the Kotzker saw him, he roared "It says מורא רבך כמורא שמים - Your fear of your Rebbi should be like your fear of Shomayim. How many 'Shomayims' are there??"
The Chossid ran out of the room with such terror that his kippah fell off.
Until now there was ONE authority in the Sefardi world to whom many [although not all] felt subordinate. Now that he is in the world that is koolo Torah, it is FRIGHTENING what will transpire. Now there are MANY different Rabbonim and of course many people feel that they have NO Rebbe, which is the most dangerous.
The tikkun is of course to bring Chacham Ovadiah back to life [and the Lubavitcher Rebbe and Rebbe Nachman for their Chasidim who are left bereft of a Rebbe].
