Euphoria.
Elation.
Exaltation.
Ecstasy.
These are the 4 states of Happiness in order. Theory says all the states are experienced only and only when you are in LOVE. That's what the magical power of love is, which drags you slowly in an ecstatically jubilant state where you know only the entry but not the exit.
If you are forced exit then you enter into a perpetual state of Melancholia where you become simply inert to anything else in the world...
I have experienced all 5 states now...
