Chassidut Chabad (Lubavitch) is celebrating its great day tomorrow: Rebbe Menachem Mendel Schneerson's Yahrzeit.
Some Chabadnikim admit that the Rebbe really passed away. The Meshichistim within the group see Gimmel Tammuz as a day when the Rebbe became invisible for our own eyes. He still resides in 770 but went up into higher spheres. When the times comes, he will reveal himself as Meshiach.
