Zot Chanukah

Apparently, there are a number of reasons, some kabbalistic, why the last day of Chanukah is called Zot Chanukah ("This is Chanukah.")  Not being mystically inclined, I prefer a more rational explanation--even though the first night's light was not unusual, since there was enough oil for one night, we express our gratitude for the ordinary miracles as well as the extraordinary ones.  Enjoy Chanukah's last hurrah.
