Kislev 9 is both the birthday and day of passing of Rabbi DovBer of Lubavitch, son of and successor to the founder of Chabad Chassidism, Rabbi Schneur Zalman·of Liadi. Rabbi DovBer was known for his unique style of "broadening rivers" -- his teachings were the intellectual rivers to his father's wellspring, lending breadth and depth to the principles set down by Rabbi Schneur Zalman.
Born in Liozna, White Russia in 1773, Rabbi DovBer was named after Rabbi Schneur Zalman's mentor and teacher, Rabbi DovBer of Mezeritch, who had passed away on Kislev 19 of the previous year. Rabbi DovBer assumed the leadership of Chabad upon his father's passing in 1812. In 1813 he settled in the town of Lubavitch, which was to serve as the movement's headquarters for the next 102 years. In 1826, he was arrested on charges that his teachings threatened the imperial authority of the Czar, but was subsequently exonerated.
Rabbi DovBer passed away on his 54th birthday in 1827, a day before the first anniversary of his liberation (see calendar entries for tomorrow, Kislev 10).

To one whose self is his body, death of the body is death of the self. But for one whose self is his love, awe and faith, there is no death, only a passing. From a state of confinement in the body, he makes the passage to liberation. He continues to work within this world, and even more so than before.
The Talmud says that Jacob, our father, never died. Moses, also, never died. Neither did Rabbi Judah the Prince. They were very high souls who were one with Truth in an ultimate bond—and since Truth can never die, neither could they.
Yes, in our eyes we see death. A body is buried in the ground, and we must mourn the loss. But this is only part of the falseness of our world. In the World of Truth, they are still here as before.
And the proof: We are still here. For if these high souls would not be with us in our world, all that we know would cease to exist.
