This was a little something I devised myself. Back in 2013 when I reconnected with fire, I realised I had missed meditating by candle light.
You can do this for yourself, for your gods (if any) your spirits (ditto), the middle bit is optional, or for whatever you feel….
“I light this fire,
For my Gods,
For my ancestors,
For the spirits around me.
May my inner fire warm me,
May my inner light guide me,
May my inner flame inspire me.”
