My zeide often said that a Rebbe is a likeness of Heaven. In Leningrad right after Sukkos — I think it was 5686 (1925) — Chatzya Lukovir (R. Yechezkel Feigin, may G-d avenge his blood, who was then the mashpia and mentor of Tomchei Temimim in Nevel) told me that when he went to speak with the Rebbe about Tomchei Temimim, the Rebbe told him, “I cannot talk to you about Tomchei Temimim; things are in a state of Tohu now. After Shabbos Bereishis, with the start of Parshas Noach and the birth of Avraham — Tikkun — then we can discuss matters.”57
57. Tohu and Tikkun: “chaos” and “rectification.” Kabbalah explains that at the beginning of creation — described in Parshas Bereishis — the world was in a spiritual state of Tohu, a lofty realm of existence which, lacking balance and order, “collapsed” in an event called "sheviras hakeilim" (the "breaking of the vessels"), when their light departed from them. This “break” — orchestrated by G-d — enabled the existence of the orderly world of Tikkun, possessing lesser light, but with abundant vessels.
