Bliss

the evolution of a human being to an enlightened being probably takes this route - you start by learning how to do some thing, then move on to understanding what you are doing, and on to understanding why you are doing some thing. i think the end state is when you go beyond the why and realise that you are doing because you are doing and not doing because you are not doing. things are because they are and things are not because they are not. this is probably the state of eternal bliss.
