Halakhah for Megillah 55:23

And we will explain the dwelling of the Divine Presence in this place in this way according to the simple understanding: Even though, in truth, our Rabbis, may their memory be blessed, said (Megillah 28a) [that] their sanctity is upon them, even when they are desolate - which implies that there is no reason at all for the dwelling of the Divine Presence from the side of the worshipers - [still,] it is possible to say that God chose this place to bless from it people that He crated, as we have said. And [just] like it was His desire to send a prophet to people to teach them the path in which they should walk and [so] merit to preserve their souls, so too did He desire, in His great kindnesses, to fix a place on earth for them that would be prepared for the good of people and their merit - and all of this is from His kindnesses to His creatures. And regardless, blessing and holiness will increase there according to the good actions that people do there. And then with the good actions, the channels of good will open up corresponding to it; since in truth the holiness of a place in its destruction is not similar to its holiness in it inhabitation (use).

And this commandment is practiced by males and females. And even at this time, one who enters there and is impure according to the guidelines that we wrote, will be liable for excision - since the holiness of God is upon it, even today when it is desolate. And [it is] like they, may their memory be blessed, expounded (Megillah 28a) from that which it is written (Leviticus 21:31), "and I will make your sanctuaries desolate," as I wrote above in Acharei Mot (Sefer HaChinukh 184).

And this commandment that one impure should not enter is practiced both by males and by females at the Temple Mount even in our days, and like the matter stated by the verse (Leviticus 26:31), "and make your holy places desolate" - and they, may their memory be blessed, expounded (Megillah 28a), "Their holiness is upon them even when they are desolate." And [it is] as I wrote above (Sefer HaChinukh 184, 363).
