Every evening, the priest would kindle the seven lights of the menorah in the Holy Temple. Miraculously, although six of the seven candles would burn out, the western lamp would remain lit until the following evening. (See link below for the exact identity of the western lamp.)
During the reign of the idolatrous King Ahaz (father of the pious King Hezekiah), this miracle discontinued. The first time the western lamp was found to have extinguished was on 18 Menachem Av (or, according to other versions, 17 Menachem Av). (Shulchan Aruch, Orach Chaim 580:2)

Sixty-seven Jewish men, women and children were slaughtered, and scores wounded, raped and maimed, by their Arab neighbors in the city of Hebron, who rioted for three days amid cries of "Slaughter the Jews." The killings began on Friday afternoon, 17 Av, and most of the victims lost their lives on Shabbat, 18 Av. The survivors were forced to evacuate to Jerusalem, and the ancient Jewish community of Hebron, which had lived in relative peace in the city for hundreds of years, was not revived until after Israel's capture of Hebron in the 1967 Six Day war.

During the summer months, from the Shabbat after Passover until the Shabbat before Rosh Hashahah, we study a weekly chapter of the Talmud's Ethics of the Fathers ("Avot") each Shabbat afternoon; this week we study Chapter Four.
Your soul is full of words, some inscribed, some engraved.
The words inscribed on your soul are like ink upon a page. They came to you from the outside, from life and its experiences. Eventually, they may fade and fall away, to be replaced by other words.
The words engraved are of the soul itself—just as engravings are no more than the form of the stone. When the soul finds quietude, those words are there. If the soul is in turmoil, or soiled by experience, those engravings need only be cleaned and uncovered. But they can never be torn away.
Those same words that are engraved in your soul are also engraved in a holy fire within the depths of the Soul of All Things. They are the words that Moses heard and inscribed on stone and on parchment. They are the words of the holy sages of Torah who found them within their own souls.
Immerse yourself in the words of Torah, allow them entry to touch your soul. Listen quietly, and you will hear those same engravings resonating within your soul.
