Capri, once again you're reminding me of ideas I've heard...and have trouble articulating...but here goes...
1) I love the scene in the movie Nell where Jodie Foster (playing Nell) makes the comment that people like her (attuned to nonverbal communication, and feeling greater truths in life) can recognize each other. (she made eye contact with the woman who was experiencing depression.)
2) I heard Judy Collins make a statement on the stage one time about how people in the arts and music just seemed to understand things and communicate on a level that most folks never experience.
I love the word joy too. Let me also add the words rejoice and celebrate.
