Defining a Hamilton-Jacobi characteristic function $W$ as the imaginary part of the $\ln Ψ$ we can recover the classical solution, and quantum corrections. The key idea is to let the energy of the Wheeler-DeWitt equation vanish only after the semiclassical limit is taken.RevTex, 7 pages, no figures; the methodology is clarified and references addedGeneral Relativity and Quantum Cosmologytext
