"...this Shabbat is called "Shabbat Chazon" after the first word of the book of Isaiah which is the Haftorah for this Shabbat.
Chazon means 'vision' or 'seeing'.
This Shabbat, if observed with joy and concentration, maximizes the possibility
for unity with G-d.
One may benefit from this state of unity and be granted an opportunity for unique and penetrating vision into not only his personal spiritual status, but also into that of the entirety of the Jewish people as well."
"Shabbat is a special day when our inherent eternal connection with Hashem is activated. There is never any mourning on Shabbat. On Shabbat we all rise up from mourning to delight in eating, drinking, festive clothes and new fruits. Therefore, the Shabbat preceding the 9th of Av is especially suitable for the kind of repentance of 'doing good' through visualizing the Temple. The purpose of the vision is not just to comfort us, but to inspire us and elevate us to turn the vision of the Third Temple into physical reality."
