• The nature of asymmetric ground states in invariant theories is discussed for the cases in which Coulomb type interactions are absent from the original equations of interacting fields. It is pointed out that such ground states can be created only by the Bose-Einstein condensation of bosons, the energy spectra of which are gapless. The latter bosons obtain certain symmetry quantum numbers in course of the dynamical rearrangement of symmetries. The Bose-Einstein condensation gives rise to a set of dynamical spurions. The considerations are shown to provide a good qualitative picture of the behaviour of systems with asymmetric ground states.
