The gemara in Pesachim (50a) says that Olam HaZeh is not like Olam Haba. In Olam HaZeh when something good happens we thank Hashem with the Bracha of HaTov V’HaMeitiv. When something bad happens we make the Bracha Dayan HaEmes. In Olam Haba there is only one Bracha, HaTov V’HaMeitiv. This because in Olam Haba we see the truth and understand that everything Hashem does is for the good.
What if you are wise person and a big Ba’al Emunah? Now, something bad happened and you want to make a Bracha of HaTov V’HaMeitiv because you believe it is truly a good thing that Hashem, the master planner, is doing for you. Surely your lofty soul should be able to sing the Bracha of HaTov V’HaMeitiv, no? No, it may not. You must say the bracha of Dayan HaEmes. In fact the gemara says in Brachos 60a that if your land is flooded you must say Dayan HaEmes, even though you are happy since this will make your land much more fertile in the future. Why?
Maybe we can answer with a Mashal. Light contains the seven colors of the rainbow. Yet we cannot see multiple colors only a single bright light. When you view the light through a prism, the light is separated into its various colors and the full splendor of the individual colors comes out.
Similarly in this world when things are to good very for us, it is very difficult to see Hashem. We cannot see his actions behind the great light. Like the pasuk says in Eikev (8:14) “V’Ram Livavecha V’Shachachta Es Hashem Elokecha”, when you acquire wealth, your heart will become haughty and you forget Hashem. In this world tears are the prism through which Hashem’s light becomes most visible to us. Sometimes only tragedy can open our eyes and make us look at Hashem. Tears come from the depths of our Neshama. It is the neshama’s outlet into a world that refuses to listen to its call from within. Tears are the fluid that cleans the dirt off our eyes so that we can see Hashem’s light once again.
Tisha B’Av is a day when Hashem wants to see our tears so that we can see him. Through our tears during the Churban, we were able to see, in plain sight, that although the Bais HaMikdash was burning and Am Yisroel was being slaughtered, the Keruvim representing Hashem and his nation, were embracing with unparalleled closeness.
On Tisha B’Av Hashem wants to see that our Neshamos still function and our Yiddishe Heart is still pumping. He wants to see that we still have feelings for our Father in heaven, who has hidden from us for so long. Hashem has made it a day of tragedy upon tragedy throughout history, to help us get the tears out. Dry eyes, say the Baalei Mussar, are a sign of a lost soul. With two thousand years of darkness behind us, and poor visibility ahead of us, let’s start the tears flowing again. Our tears on Tisha B’Av will bring about the birth of Moshiach, who together with our corrected vision will help us be zocheh to see the light of Hashem, Milo Kol HaAretz Kivodo. Revach.
