Exuberance

" "Exuberance" derived from the Latin exuberance― ex, "out of," + uberare, "to be fruitful, to be abundant"― is as its core a concept of fertility.  Exuberance in nature is defined by lush, profuse, riotous growth; it is an overflowing, opulent, and copious abundance.  ... In our time, "exuberance" usually denotes a mood or temperament of joyfulness, ebullience, and high spirits, a state of overflowing energy and delight.  It is more energetic than joy and enthusiasm but less intense, although of longer duration, than ecstasy.  The origins of the concept of exuberance in the cyclic fertility of nature, now largely forgotten, remain critical to understanding it as a primitive life force vital to survival."
-  Kay Redfield Jamison, M.D.  Exuberance: The Passion for Life

"The Greeks understood the mysterious power of the hidden side of things.  They bequeathed to us one of most beautiful words in our language― the word 'enthusiasm'― en theos― a god within.  The grandeur of human actions is measured by the inspiration from which they spring.  Happy is he who bears a god within, and who obeys it."
-  Louis Pasteur
