This morning I studied Pirkei Avot (Ethics of Our Fathers) with a friend and we had the great pleasure of completing the entire book after many months of weekly study. The final paragraph of this timeless treasure of Torah insight and wisdom states that everything in our world was created for the purpose of glorifying G-d - our creator. Fundamental to Jewish belief is the idea that everything is an expression of G-d and can teach us something unique in perfecting our lives and the world around us. Coronavirus is a big deal and every day it affects more and more people. Countries are shutting their borders, markets are tumbling and world leaders are hard pressed to find solutions. On a personal level, my family members who serve as Chabad emissaries in China were compelled to leave in haste and their communities have been displaced. What can be “glorious” about this uncontrollable nightmare? The physical, emotional and financial toll this health menace is having on so many is terrible and I pray it all comes to a swift end. But coronavirus is one of the greatest illustrations of an important Torah message that we often find hard to relate to. The source of the coronavirus is believed to be a "wet market" in Wuhan, China. The poor hygiene created the perfect setting for infections originating from bats to spread to animals sold there. Think of it: a few infected chickens in Central China allegedly caused a public health crisis currently gripping humanity with fear. In this week’s parsha we learn of the mitzvah to build the Mishkan (tabernacle) in the Israelite camp in the desert as a traveling temple for G-d. Hundreds of years later King Solomon built the Beit Hamikdash (Holy Temple) in Jerusalem which he designed with “narrowing windows.” Typically windows then were designed to be narrow on the outside and wider on the inside to diffuse the outside sunlight inside the structure. But these were designed narrow on the inside and wider on the outside symbolizing the fact that the Beit Hamikdash is not illuminated from the outside light, rather the entire world is illuminated by the divine light emanating from the Beit Hamikdash. When G-d communicated the instructions to build a Beit Hamikdash to Moshe He said “Make a sanctuary for Me so that I may dwell within them.” Even in the absence of the physical Beit Hamikdash, twice destroyed thousands of years ago, its function continues through every one of us, and we need to have “narrowing windows;” to be a source of light and inspiration to the entire world. Never underestimate the impact your one mitzvah can have on the entire world. If illness can be viral, goodness most certainly can be as well. And when we all appreciate this truth and act upon it joyfully, we will prepare the entire planet for an era of peace and tranquility for all, when all illness will cease, with the coming of Moshiach.
