I doubt that all there was to this visit and all you felt was just the experience of that day.
I have a feeling that a day will come and something will seem to light up inside you and you'll have that moment of knowing why it called to you and you will have grown again.
You often seem to take little trips, in...maybe in little spurts...but at least, far more often than I do. Mine seem to come once a decade or two...I envy you my friend, I hate stagnation.
