In witchcraft traditions, ritual (as far as I can tell from the outside) is what you do in order that a group of people can do magic together. There’s also an aspect of celebrating the seasons and honouring deity and the natural world.
Ritual for Druids is often more about the celebration, and less about deliberate intent to perform magic. There are groups and individuals who approach Druid ritual for magical purposes, but my experience has been that the majority gather to celebrate, above and beyond all else. It’s one of the reasons Druid rituals are more family friendly, because there isn’t the same demand for deep focus and intensity that collective spellwork requires.
Having said that, Druid ritual has the capacity for magic. It is more likely to be an emergent property rather than something intentioned. I’ve seen that magic take many forms, here are a few examples.
A growing sense of connection and community that changes how people relate to each other.
Empowering participants such that they find their own voices and creativity and are able to stand in their own power.
Connecting people with the land and seasons in a way that radically impacts on who they are and what they do.
Giving power to vows, dedications, offerings and intentions such that a person is more inspired to see it through, more invested and more able. Bringing the sacred to our commitments.
Feeling witnessed, heard, seen and held in the context of ritual space can be an incredible and transformative experience for a person.
Inspiration / awen, shared or individual, arising within the ritual can lead to wild creativity and improvisation, and again can change people in all kinds of ways.
A sense of the numinous can be a consequence of ritual.
