While the geometric model shares the essential principles of the causal interpretation initiated by de Broglie and advanced by Vigier, the particle and wave components of the theory are derived from the Einstein equations rather than a nonlinear wave equation. This geometric approach leads to several new features, including a solution to the de Broglie variable mass problem.12 pages, Latex, to be published in the "The Present Status of the Quantum Theory of Light", proc. of symposium in honour of J-P.
