4. Today is a unique day in the Jewish calendar. It is the eighth of Tishrei, the day on which King Solomon initiated the dedication of the Bais HaMikdash in Yerushalayim.[35] The Temple is connected with the service of Teshuvah. For that reason it was constructed of stone, showing the relationship to the service of “the elevation from below.” The First Temple, whose construction was aided by Chiram King of Tyre, emphasized that quality of elevation. His participation demonstrated (even the) elevation of the gentiles.
This concept is also obvious in comparing the Bais HaMikdash to the Sanctuary built in the Desert. The Sanctuary represented the service of Tzaddikim; therefore, its dedication was in Nissan, a month of revelation from above. The Bais HaMikdash represented the service of Ba’alei Teshuvah; therefore, its dedication was in Tishrei, a month which emphasizes man’s service. The service of Teshuvah brought about the great joy and celebration which marked the dedication of the Bais HaMikdash. in fact the joy was so great that the Jewish people ate and drank on Yom Kippur. Later, when they questioned their behavior, a heavenly voice answered, “A portion for all of you is reserved in the world to come.” Their celebration with food and drink was able to bring about a greater effect than the normal service of fasting. more@SichosInEnglish
