A very simple and physical derivation of the conservation equation for thepropagation of gravitational radiation is presented. The formulation is exact.The result takes the readily recognisable and intuitive form of aPoynting-style equation, in which the outward propagation of stress-energy isdirectly related to the volumetric equivalent of a radiation reaction forceacting back upon the sources, including the purely gravitational contributionto the sources. Upon averaging, the emergent pseudo tensor for thegravitational radiation is in exact agreement with that found by much morelabour-intensive methods.
