Two previously given theories are unified, facilitating the discussion of ray tracing in nonlinear and absorbing media. The media may be fairly general: dispersive, absorbing, anisotropic, inhomogeneous, and time varying. Self-focusing is demonstrated on a simple example, showing that absorption will slow down the buildup of high intensities expected from the convergence of the rays.
