If Chazal say: לָכּהָּתָחְמִשְׂב הֶאוֹרְו הֶכוֹז םִיַלָשׁוּרְי לַﬠ לֵבַּאְתִמַּה תענית ל ב “Whoever mourns over Yerushalayim, will be Zoche to see its Simcha”, then being all broken these days about the Bais Hamikdash is worth millions. In the end, those people will have much more Simcha than all their friends.
Remember the delicious Lechem HaPanim and the beautiful Menorah and the: ִניסוּ˂ ַהַי ִי ן wine that was poured on the Mizbeach after the Korban, and: ִניסוּ ˂ ַה ַמ ִים the water that was poured on the Mizbeach during the seven days of Succos, the dazzling Simchas Bais HaSho'eva, the giant: וּא ָלם Ulam, the Heichal and Kodesh HaKodoshim! And imagine those Z'rizus’dik Cohanim running to do Avoda with such a Geshmak and Simcha, and the city of Simcha (Yerushalayim) where you weren’t allowed to do a math problem, since for a few minutes you’re sad until you figure out the answer.
Imagine yourself and your friends marching upwards to Yerushalayim with beautiful Bikkurim fruits, singing: תיֵבּ יִל םיִרְמֹאְבּ יִתְּחַמָשׂה' ˂ֵלֵנ תהלים קכב א I rejoiced that they said to me: "Let us go to the house of Hashem ", and once they entered Yerushalayim, they said: םִָלָשׁוּרְי ˂ִיַרָﬠְשִׁבּ וּניֵלְגַר וּיָה תוֹדְמֹע תהלים קכב ב “Our feet stood within your gates, O Yerushalayim (i.e., our feet stood still within the gates of Yerushalayim, as if transfixed by the view of the city which spread out before our eyes. RSRH). Watch all the Chashuva Cohanim coming out to greet you, and all Yerushalmi shop-keepers standing up for you and giving Kavod to you and all your friends. Imagine how Geshmak was the Torah and Tefila those days!
