Today is the seventh day of Chanuka. "Seven" in Judaism signifies extra holiness, such as the Sabbath (the Seventh Day) and Shmitta (the Seventh or Sabbatical Year).
A spark of of holiness can destroy a mountain of evil. Evil is usually bloated and overblown, basically lacking real power. Holiness is compacted, and oftentimes hidden from the eye. A spark of holiness totally deflates a giant blimp of evil, just as a spark from the blacksmith's anvil can burn an entire haystack. As long as a person is immersed in holiness, he or she has nothing to fear from evil - ever!
A spark of faith, a few psalms recited from the heart, a page of Gemara, an hour of personal prayer in the field, lighting Chanuka candles with the family - these are only a few examples of high-level holiness that can protect you and yours from any evil, and illuminate your soul.
Kedusha (holiness) is the weapon that enables the weak to defeat the strong, the few to overcome the many, and the righteous to outdistance the tyrannical. May we soon merit to see the lights of Chanuka in our rebuilt Temple in Jerusalem, amen. Happy Chanuka!
