Query: Reply to ``Comment on 'Two Fermi points in the exact solution of the
  Kondo problem'''   In his Comment N. Andrei questions the use of symmetric limits of integration
of the Bethe ansatz integral equations in my recent study devoted to some
features of the Bethe ansatz solution of the Kondo problem. In this Reply I
show that the statement of the Comment about the asymmetry of integration
limits contradicts the distribution of the quantum numbers in discrete Bethe
ansatz equations. I also argue that the asymmetry of the excitation energy
supported in the Comment conradicts the initial chiral symmetry of conduction
electrons in the physical Kondo problem. Hence the distribution of spin
rapidities has to be symmetric for any magnetization.
