As usual Carpe Diem has given us an interesting challenge. The post containing it deals with the burning of ornaments at a fire festival. This is about leaving the old and taking on the new.
Fire is the medium for getting rid of whatever is holding you back. I think many religions, particularly Pagan ones, have a fire festival with this theme.
My haiku for this challenge is:
The New Year bonfire;
its white smoke rises skywards.
The flames warm my hands.
