•The variational method is an extremely useful approximation method .  Many of the Hamiltonian cannot be separated into a solvable part and the perturbation part. For such cases, there is no good starting point to apply the perturbation theory.  The variational method can be used to solve such problems and many others where other approximation methods are too difficult to employ.
