Abstract
Relativistic covariance requires that in the constituent quark model f or mesons the positive energy states as well as the negative energy st ates are included. Using relativistic quasipotential equations the con tribution of the negative energy states is studied for the light and c harmonium mesons. It is found that these states change the meson mass spectrum significantly but leave its global structure untouched.
