R. Shimshon of Ostropolle was a saintly individual who was greatly revered both in his lifetime and beyond. It is told that an angel called a maggid would come and reveal secrets of Torah to him, and that he merited revelations from Elijah the Prophet. He himself records kabbalistic insights that were revealed to him in dreams.
R. Shimshon authored Dan Yadin, a kabbalistic commentary, as well as numerous other unpreserved works. Additionally, many of his interpretations that were preserved orally have been collected and published.
R. Shimshon died a martyr’s death at the hands of a Cossack mob during the Chmielnicki Massacres, while wrapped in his tallit and tefillin.

During the “Nine Days" from Av 1st to the Ninth of Av, we mourn the destruction of the Holy Temple. We abstain from meat and wine, music, haircutting, bathing for pleasure, and other joyous (and dangerous) activities. (The particular mourning customs vary from community to community, so consult a competent halachic authority for details.)
Consumption of meat and wine is permitted on Shabbat, or at a seudat mitzvah (obligatory festive meal celebrating the fulfillment of certain mitzvot) such as a brit (circumcision), or a siyum celebrating the completion of a course of Torah study (i.e., a complete Talmudic tractate). The Lubavitcher Rebbe, of righteous memory initiated the custom of conducting or participating in a siyum on each of the Nine Days (even if one does not avail oneself of the dispensation to eat meat).
Citing the verse "Zion shall be redeemed with mishpat [Torah] and its returnees with tzedakah," (Isaiah 1:27) the Rebbe urged that we increase in Torah study (particularly the study of the laws of the Holy Temple) and charity during this period.

This is my G‑d, and I will praise Him, the G‑d of my father, and I will exalt him.
Exodus 15:2
When He is only the G‑d of your father, He remains exalted and beyond your world. When you make Him your own G‑d, then you can truly praise Him with your heart.
Rabbi Isaiah Horowitz (16th century)
Only a fool will toss out the inheritance of many generations. But one who does not take ownership remains a child.
So it is with a material estate, so it is with the faith of our fathers and mothers. We must make it our own faith, as well.
And how do you make that faith your own? Ironically, through the power of your own mind.
Engage your mind to live by your faith.
