The fifth aliyah (section) of Parshas Terumah mentions the structure and function of the paroches, the dividing barrier between the Kodesh (Holy) and Kodesh Hakedashim (Holy of Holies). During the times of the Beis Hamikdash, we were able to see the presence of Hashem when we went to Jerusalem on Pesach, Shavuos, and Sukkos and the paroches was moved aside. This is in stark contrast to the times of the mishkan when even the Bnei Kehas, who had the job of carrying the vessels of the Kodesh Hakedashim, were only able to see the vessels after they had been covered. The Beis Hamikdash was Hashem's permanent home, where He invited us so to speak, as opposed to the Mishkan which was a temporary dwelling place used while traveling. The permanent home bespeaks a certain level of comfort, which is why we were able to see Hashem's presence and maintain that intense closeness. - Library: Bnai Jacob Shaarei Zion - RabbiHauer.org
