The Jewish community of Ostroh (in what is now western Ukraine) was miraculously spared when a Russian army led by General Suvorov attempted to breach its walls, claiming Polish insurgents were present inside. To commemorate the miracle, the day of 7 Tammuz was established as a local day of rejoicing, and a special scrollin which the story was inscribed was read each year on this date.
According to legend, two cannons that struck the great Maharsha synagogue caused no harm. The two cannons were thereupon displayed in the synagogue for all to see. (Yalkut Volhynia,issues 2–3)

Once a month, as the moon waxes in the sky, we recite a special blessing called Kiddush Levanah, "the sanctification of the moon," praising the Creator for His wondrous work we call astronomy.
Kiddush Levanah is recited after nightfall, usually on Saturday night. The blessing is concluded with songs and dancing, because our nation is likened to the moon—as it waxes and wanes, so have we throughout history. When we say this blessing, we renew our trust that very soon, the light of G‑d's presence will fill all the earth and our people will be redeemed from exile.
Though Kiddush Levanah can be recited as early as three days after the moon's rebirth, the kabbalah tells us it is best to wait a full week, till the seventh of the month. Once 15 days have passed, the moon begins to wane once more and the season for saying the blessing has passed.

True, our hearts are not in our hands. But our minds are: We can think about whatever we decide to think about. And therein lies our power.
The mind rules over the heart—not just as a rider rules over his horse, but in a much more intimate sense. For the mind is the father and the mother, the seed and the womb from which the attitudes of a person are born and then nurtured. The heart does no more than reflect the state of the mind—its turmoil, its resolution, its shallowness or its depth, its coarseness or its maturity.
This then must be the focus of the person who wishes to leave this world with more than he arrived: To engage his mind with all its intensity in thoughts that elevate and inspire, and push away with equal force any thought that drags down and holds back.
And to allow all that labor to pass through the channel from the mind to the heart and give birth to actual deeds.
