Using the analogy with the nonrelativistic potential quark model for the spin-spin splitting of the hadron masses, we give a unified description of the parameters of the light hadrons (the octet and decuplet of baryons and the octets of vector and pseudoscalar mesons including the pion) in the framework of the MIT bag model and of the chiral invariant bag model. We estimate the contributions of the quark and pion phases to the pion-nucleon sigma term. We discuss the contributions of the pion phase to other hadron parameters.
