Enlightenment

         Enlightenment is attained in the context of having the knowledge that you can-and will- never know all there is to know in the world.

         Within that context, the precise definition of enlightenment is contentment in the search, and the wisdom of realizing that even though you will never learn all there is to learn, that makes each bit of knowledge all the more precious. It leads to a more complete (yet never complete) person.

         Basically it's finding happiness in the quest for knowledge even though you know it's futile. Don't confuse happiness with joy. Being in a state of perpetual joy is entirely possible.

Total (100%) Happiness...
    on the other hand, is quite impossible to obtain.
( BLISS and/or CONTENTMENT IS possible! )

After all, what is the point of knowledge if you can not understand it?

         Although the question has never ever been answered, no one being has ever been capable of obtaining all the knowledge in the world.

          When one thinks one know it all- something new will develope of which you know nothing about... you might be enlightened by it's existance, but not neccesarily knowledgeble to it.

It is, by definition,
education that results in understanding and the spread of knowledge
... to give spiritual insight to surroundings, and one's being.
