He established a factory to provide employment for the poor, and endlessly gave away his money to the needy. traveled extensively throughout the Russian empire. He was a member of the right extremist movement Sojuz Russkogo Naroda (Alliance of the Russian people) but did not commit himself politically. He was already greatly venerated at the time he died. He was glorified by the Russian Orthodox Church Outside of Russia in 1964 and by the Russian Orthodox Church on June 8, 1990.
