The word Havdalah means to differentiate, to distinguish. The entire ceremony is to distinguish between the Shabbat that we have just experienced and the week that we are about to enter. In the Havdalah ceremony, we set a braided candle aflame and hold up our fingers to see the light and shadows dancing upon them. Shabbat is over. We mark the ending with Havdalah and recognize the beginning of the week. For the week is not Shabbat. If we have used the Shabbat properly however, we may be able to infuse some of it into our week.
