I would like to find the Russian original of one of the presumably very few chasidic works written in that language. The work in question is בד קדש, addressed by the Miteler Rebbe, Rav Dovber of Chabad, to Governor-General Chavansky, of Vitebsk, in 5586-5587.
It appears here in English translation by Eliyahu Touger and Shalom Ber Wineberg as part of a sefer about the Miteler Rebbe's liberation from prison. The letter, which reworks an older discussion by the Alter Rebbe of the sefira of Malchus, including some very interesting comments on the definition of beauty, was a main catalyst for that liberation.
I do not know the Russian title of this work, but one possible transliteration is "Бад кодеш." Any help finding the original either in print or online would be appreciated. Thanks!
