The marking of a good thing so it is not passed over. Celebration is attention given deliberately to what went right.

Finished, with nothing remaining. Done must be defined in advance or it never arrives.

The festival of colors — spring celebrated by throwing every hue at once; a palette name wearing the joy.

Those gathered — for celebration, or as a side in an exchange; the line where both meanings meet is consent.

The reaching of what was aimed at. Success is measured against a stated aim, which is why an unstated aim can never be met.
