We show that the effects of hadronization, confinement, spontaneous chiral symmetry breaking and $η_0$-meson mass can be hidden in solutions of the non-Abelian Gauss constraint in the class of functions of topological gauge transformations, in the form of a monopole, a zero mode of the Gauss law, and a rising potential.Invited talk at the XV Inernational Seminar on High Energy Physics Problems (ISHEPP), JINR, Dubna, September 25 - 29, 2000High Energy Physics - Theorytext
