I suggest that what you described in limmerance.
Thanks for your post. I love learning new words!
Words, and the concepts they represent, are the tools the mind uses to organize our mental universe. They are the building blocks of understanding. When I looked up limerence it was described as "an involuntary state of mind resulting from romantic attraction". Perhaps that is the reason we value it so highly, because it is not an experience that we can create in isolation.
Then we have the added concept that if we live our lives in certain ways, and dedicate ourselves to certain ideals, we can increase the frequency and intensity of what is essentially an involuntary experience. This is sort like saying "I cannot create the sensation of a pleasant fragrance, but I can bend over and put my nose to flowers more often".
So my new definition is "Love is that pleasant, involuntary state of mind which can occur as a result of a relationship with an object outside myself". Hmmm, that definition doesn't seem perfect. But, like me, it is still a work in progress.
