What the Saint John's fires really burn: an ancestral purification ritual.

The night of June 24th. Bonfires are lit all over France. In villages, on beaches, in gardens. For most people, it's just folklore. A relic of the past. An excuse to stay out late on a summer evening.

But the bonfires of Saint John are one of the oldest purification rituals in Europe. They predate Christianity by several millennia.

Long before Saint John's Day, Celtic, Germanic, and Slavic peoples lit fires at the summer solstice. The idea was simple and profound: fire purifies.

Water cleans the surface. Fire cleans the depths.

The jump over the flames

We jumped over the flames to leave something behind. Each jump was a physical release. The body rose above the fire. And falling back down on the other side, we landed lighter.

It wasn't symbolic. It was sensory.

The heat on the skin. The smell of smoke. The crackling of the wood. The dizzying feeling of jumping. All the senses activated at once. The brain receives a powerful message: something has changed.

And when the brain believes that something has changed, the body follows.

It's the same principle as a rite of passage. A baptism. A wedding. A graduation. The brain needs markers to register change. Fire is humanity's oldest marker.

Fire herbs

The herbs that were burned were not chosen at random.

Sage — purifying, antiseptic, calming for the nervous system. Rosemary — tonic, clarifying, protective. Thyme — cleansing, fortifying, warming.

The smoke from these plants was not decorative. It was therapeutic.

Inhaling sage smoke reduces airborne bacteria by 94% for 24 hours, according to a study published in the Journal of Ethnopharmacology .

Your ancestors knew it. Without a laboratory. Without a microscope. They knew it because they listened to the plants.

Your Saint John's ritual

Write down on a piece of paper what you want to leave behind on the other side of the fire. Not a list. One word. The word that sums up what weighs you down.

Fear. Anger. Regret. Guilt.

One word.

Then burn this paper. If you have a garden, light a small fire and burn it in it. If you don't have a garden, a candle will do.

Watch the letters curl up. Turn black. Then white. Then disappear.

Breathe in the smoke.

And know that what is burned does not return. The space is free. For something new.

With purification,
