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