The Mishkan was the dwelling place for G-d in this world. If G-d could have a house here on earth the Mishkan is what it would look like. The Torah goes to great lengths to describe to the Jewish people exactly how the Mishkan should be built and how it should look. This is a sort of Jewish Feng Shui: It is a lesson in how to make G-d belong in our homes and in our lives. If we can understand the architecture of the Mishkan we can understand something about how G-d relates to this world and to us.
The supporting beams of the Mishkan were a series of very large pillars, called Krashim. The Torah describes the placement of the Krashim in the very human terms of “Isha El Achosa” like sisters standing beside on another.
In the words of the Baal Shem Tov: The world is a Mishkan and we are it’s Krashim. Just as the tapestries of the Mishkan were dependent on the Krashim to form an actual structure, G-d leaves it to us to make the world into a viable and G-dly space. Just as the Krashim gave shape to the Mishkan, we are enjoined to give shape to this world and turn it into a holy structure – a place where G-d can dwell.
Often, great people are also great nonconformists. They have courage and can beat to their own drums; they will become truly great if they refuse to forget their roles as supporting actors.
We are here in this world as ambassadors of G-d. We should represent G-d in everything that we do and to everyone that we meet. We can make this world more G-dly with every nice word that we say and with every moment that we keep our mouths shut. If we can do this then we are truly Krashim. We can be pillars of the world; we can hold the whole world in our hands (and that sure beats a funny looking statue).
Based on Degel Machane Efraim. Thanks to Mr. H. Broncher of Har Nof for introducing me to this vort and to the Degel on Parshas Terumah 5759.
This put it in such simple terms even I understand.
