  We propose a method to recover the time variable and the classical evolution
of the Universe from the minisuperspace wave function of the Wheeler-DeWitt
equation. Defining a Hamilton-Jacobi characteristic function $W$ as the
imaginary part of the $\ln \Psi$ 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.
