During the seven days of festivities following the wedding of the Rebbe Rashab in Elul 5635 [1875], the chassidim celebrated with indescribable joy. On one of those days, his father, the Rebbe Maharash, sat at his window and watched them dancing in the garden in dozens of circles. Turning to the two chassidim who stood next to him, he said: “See, my children, how chassidim are glad in the joy of a mitzvah. This is how Jews will dance in the streets when Moshiach comes!”
