The eve of the feast of Samhain, marking the end of the harvest season. It was the most important of the four Celtic Festivals, the start of winter and the darker part of the year. Bonfires were lit as a reminder of the victory of light over the increasing dark days.

When you do something,

you should burn yourself completely,

like a good bonfire,

leaving no trace of yourself.

Shunryu Suzuki
