That is, even if the Exile hinders us from carrying out our true desires, nevertheless the very desire and passion to be good is something with which G-d is not displeased. This is man's job: to desire good. 

Rabbe Nachman of Breslov also wrote on this topic, shining a light on the force of one's true desires: "The Israelite man who truly wants the truth, and does not want to fool himself – then even when [negative] passions and inhibitors overcome him, as they often do, and place themselves before him in all directions to the point that he cannot withstand them – even then, no matter how far he [has been taken], he still longs and yearns all the time for the blessed G-d, and never abandons this will and longing; it is very, very precious in the eyes of G-d, and He praises Israel for this, and it is because of this that they merit what they merit."

This approaching Sabbath is called Shabbat Hazon, which literally means "the Sabbath of vision" (it is named after the "vision" of the Prophet Isaiah of which we read in the Haftarah).

The righteous ones say, and show various signs, that this Sabbath is the holiest one of the year. 

Our Sages taught that whoever mourns for Jerusalem, "merits and sees its [future] happiness." Why is this stated in the present tense, and not the future tense? 

The answer has to do with the fact that we don’t mourn on the Sabbath, not even for the Holy Temple. Our Sabbath Grace After Meals includes the words, "may there not be tribulation and sadness on our day of rest." For the main asset and positive feature of the Beit HaMikdash is having the Shechina (Divine Presence) in our midst – and on the Sabbath, the Shechina is with us even in the Exile. 

We know this from the well-known fact that we may not perform any Sanctuary-related work activities on the Sabbath – for on the Sabbath we do not need Sanctuary activities, because the Shechina is present then regardless. On the contrary, the Sages teach that whoever makes sure to have Sabbath enjoyment, receives "boundless inheritance." That is, the most genuine enjoyment occurs when one believes that G-d is in our midst – and this is a "boundless inheritance."

Taking this a bit further, we can understand that on these Sabbaths of the Three Weeks of mourning, and particularly this final one coming up this week, the sensation of G-d's presence reaches its height – because during these weeks we mourn more intensely for Jerusalem and the loss of Divine honor with the loss of the Temples. As such, if on a regular Sabbath we have "boundless inheritance," how much more so right now, on the Sabbaths that are intertwined with mourning for the Temple - and especially on Shabbat Hazon! 

That is, these very days help us to mourn for Jerusalem, and therefore in the present – these very Sabbaths – we get to see and feel the splendor of the Temple and G-d's honor in the world even more than usual.

We must therefore make sure specifically this Sabbath to beautify the Sabbath and enjoy it, and thus be worthy of "boundless inheritance," to see the great light that is present on Shabbat Hazon, leading us to the Full Redemption.
