“This Shabbat is known as Shabbat Chazon [as] this week’s haftorah relates a vision (chazon in Hebrew) seen by Isaiah. It’s a vision of the destruction that will come to Jerusalem… [Each of us is shown a vision this Shabbat] of the rebirth that is destined to follow the destruction prophesied by Isaiah.
This is also the Shabbat that precedes…Tisha B’Av, when we fast in remembrance of the destruction of both Temples. Yet this Shabbat, as we read the Torah portion, every Jew is granted a vision of the third Temple, which will be built (G-d willing, speedily and soon) in Jerusalem.
…
This Shabbat, G-d takes advantage, so to speak, of this very aspect of human nature: that what we see, even if only with our mind’s eye, lingers with us and affects us so intensely. He shows us a vision of the future He is waiting to give us, and the vision itself becomes the tool with which we make this world ready to actualize it.
…
The Lubavitcher Rebbe emphasized that any and every individual can access this power for change in a tangible way, by meditating this Shabbat on what our soul will see, a vision of a House which will fuse the upper and lower worlds, spiritual and physical reality, in permanent union.”
