Query: Vacuum quark condensate, chiral Lagrangian, and Bose-Einstein statistics   In a series of articles it was recently claimed that the quantum
chromodynamic (QCD) condensates are not the properties of the vacuum but of the
hadrons and are confined inside them. We point out that this claim is
incompatible with the chiral Lagrangian and Bose-Einstein statistics of the
Goldstone bosons (pions) in chiral limit and conclude that the quark condensate
must be the property of the QCD vacuum.
