Samhain was a celebration of the harvest and is closely associated with the concept of autumn symbolically representing the end of life and the start of the winter cycle.
The bonfire is therefore a symbolic means of ushering in the process of rebirth.
It also works well for some school spirit.
The rebirth.. the spirit.. it burns bright.
The rebel yell in the dark of night.
Foreboding is the darkness still
Erased from time is good will.
With a fire brought until the dawn..
Accept a change and end what’s gone.
