Abstract
General aspects of chiral symmetry breaking are discussed in the context of the instanton model of the QCD vacuum. In the long wavelength limit, a Landau-Ginzburg effective Lagrangian is derived after proper coarse graining of the liquid phase. This approach leads naturally to the concept of chiral solitons much like vortex excitation in liquids. Some pertinent issues related to Skyrmions are discussed. The issue of the relevance of confinement versus chiral symmetry in low energy processes is raised in the context of the Cheshire can principle, using the flavor singlet axial current as a specific example.
