  The Hamilton-Jacobi theory of Classical Mechanics can be extended in a novel
manner to systems which are fuzzy in the sense that they can be represented by
wave functions. A constructive interference of the phases of the wave functions
then gives us back Classical systems. In a suitable description this includes
both Quantum Theory and General Relativity in the well known superspace
formulation. However, there are several nuances which provide insight into
these latter systems. All this is considered in this paper together with
suitable generalization, to cascades of super universes.
