“Prayer gates were locked”

Hello Rabbi
I have just finished reading the part of the trilogy that talks about the matter of prayer. The recurring argument is that God changed His policy regarding intervention in the world and the acceptance of prayers. There is a sage’s article that says exactly as you say, that there was a change of policy with the destruction of the First Temple: Berchot Lev, in – “And Rabbi Elazar said, From the day the Temple was destroyed, the gates of prayer were closed, as it is also said, For I will cry and be saved, my prayer is ended. And although the gates of prayer were closed, the gates of tears were not closed, as it is said… From the day the Temple was destroyed, an iron wall was broken between Israel and their Father in heaven, as it is said…”
The first part says that prayers are no longer accepted (except for special ones, and maybe that has changed already?) and the second part says that there is a disconnect between God and Israel, and He no longer leads us.
I asked – Why didn’t you include the article in the book or elsewhere?
It really helps you that since the end of the biblical period, the destruction of the temple, there is no more intervention and acceptance of prayers except for special tearful prayers that the gate was not locked (and apparently that has changed too). The one who needs to make up excuses is the one who thinks that prayers are accepted! (I have seen excuses, but they all ultimately contradict the article to one degree or another).
