We revisit Witten's proof of the positive mass theorem in a very general setting where the spinor bundle and the Dirac operator are replaced by any choice of an irreducible natural bundle and a very large choice of first-order operators. As an application, we show that it may lead to a positive mass theorem along the same lines if the necessary curvature conditions are satisfied.
