  In this article, we show -- using a reasoning applicable to both the
excitation spectrum in the chiral bag model and the hyperfine structure of
diatomic molecules -- that the generic form of a non- abelian Berry potential
appears in heavy-quark effective theory (HQET) and that the Berry potential
vanishes for the soliton- heavy meson bound state in the heavy-quark limit. The
vanishing of the Berry potential in HQET is shown to be related to the
restoration of heavy-quark symmetry in infinite heavy-quark-mass limit in close
analogy to diatomic molecules at infinite internuclear separation.
