Quality candles must be used for Shabbat but no such rule applies to Chanukah when we may use any type of candle. The human being is compared to a candle: the wick is the body, and the oil is the soul. Whereas not every person is ready for Shabbat, we are always ready for Chanukah. If wind blows out the Chanukah candles, we don’t need to relight them for as R. Shmuel of Slonim writes, “from the heavens they will help” as the Chanukah candles remain alight in every Jewish heart.
