Particularly happy

I am particularly happy in a fleeting way, or maybe a transitory way. These words aren't capturing the sentiment. I'm happy in a way that notices the peculiarly transitory nature of our existence. So while yes, I'm sure the happiness will be fleeting, it feels permanent in a heretofore unknown way. This happiness is a silent laugh at the child playing in the fountain, shivering, but with no plans to get out of the water. Silence and the quality of a traveller (and this is what I don't have a word for) - perhaps these are the revealers of such happiness. Somehow I think Chuant Tzu is correct - that to release our grip on this life reveals the ultimate humor, seriousness, friendship, happiness, and accomplishment. Shhhhh, Jonathan...
