I have been looking at the TDSE (time dependent Shrodinger equation), considered when describing a system with only 2 states.

And essentially I got confused!! Can i get a decent explanation?

To clarify I am fine with Hamiltonians, and the Hamiliton of a particle in an electromagnetic potential.

Usually $i = \sqrt{-1}$.
