Chanukah is the holiday of victory and thanksgiving. The few were victorious over the many and thanked the Almighty many many times over.
The more you give thanks, the more you receive and the more you become. To be or not to be is to give thanks or not to give thanks.
Thanksgiving is one meaning of hod, the 8th sefirah (like the 8 days of Chanukah). The others are splendor, acknowledgment, and confession.
If we acknowledge God then God acknowledges us. If we confess our bad then God "confesses" our good, and we become a splendorous reality.
