“It is appropriate for every G-d fearing person to be aggravated and worried about the destruction of the Beis Hamikdash” – Shulchan Aruch Orach Chaim 1:3
The Chidushei Hu’rim asks, why should only a G-d fearing person be upset about the Churban and not every person?
He answers “Someone who is not G-d fearing should be upset about their own Churban, i.e. that they are not G-d fearing!
Chasidus taught that the individual Yid and the collective Klal Yisroel are intertwined and essentially one thing. The churban of the individual, physically or spiritually is a churban of the Klal and vice versa. We are crying and anguished about the lack of Gilui Shechinah in every aspect, the individual and the collective.
All the problems in the world are a result of a Hester Panim, Hashem concealed himself, that’s why we are so broken and in such pain. The G-d fearing and the Not-Yet G-d fearing are crying out about the brokenness of the individual and the collective, they are both one thing.
