Rabbi Yaakov ben Meir Tam, known as the "Rabbenu Tam," was one of Rashi's illustrious grandsons. During the Second Crusade, on the second day of the holiday of Shavuot, the Crusaders entered his hometown of Ramerupt, and pillaged and massacred many Jews.
They broke into Rabbenu Tam's house, plundered all his wealth, and seriously wounded Rabbenu Tam. On the next day, the 8th of Sivan, Rabbenu Tam escaped Rameru and the clutches of the Crusaders.
Two years later he completed his famous treatise on Jewish ritual and ethics, Sefer Hayashar.
The day following a festival is called Isru Chag ("tied to the festival"). Tachnun (confession of sins) and similar prayers are omitted through the 12th of Sivan.
On Isru Chag, It is customary to hold a kinus Torah, a public gathering in which Torah thoughts are shared and discussed.
There’s nothing that matches the joy when a lost child returns home. And you are that child.
Because your soul began within G‑d.
And she descended into this world to inhabit a body and live as though a stranger to the heavens, captive of a futile dream, journeying upon many winding and perilous roads…
Until waking up one day and realizing that none of these lead back home.
And now, every day, with every prayer of your heart, with every word of Torah upon your lips, with every mitzvah and good deed you fulfill,
You are coming home.
There can be no greater joy—above and below.
