Hamiltonian Operator Versus Lagrangian

In the following multiplicit case, one may say that the general difference that is to exist, between the Hamiltonian operator and the Lagrangian, is that the respective  Hamiltonian operator, is here to be the actual physical entity of energy that is to be transferred from one spot to another, -- whereas, the Lagrangian is the actual motion, by which the said physical entity of energy that was earlier mentioned, is to be transferred from the one respective spot to another.  Samuel David Roach.
