Animism isn't universal, I'm not even sure if it was common amongst the Celts- I think that while there were objects of power within the Celts theology- these were exceptional, not common place.
That said- Eclectic Neo-Paganism doesn't have any prohibitions against belief in Animism.
Karma is very much not a part of the Celtic world view. While Karma isn't included in most western traditions, it isn't completely unheard of- what is more common is a concept of "the law of return"- and that isn't uncommon amongst Eclectic Neo-Pagans at all.
For further reading on Karma- check out The Bhagavaghita.
Here is the classic poetic translation.
Is there a particular style of meditation? I mean, we know that Zen wasn't used by the Druids. However- even without my tongue firmly planted in my cheek, I am not sure the term "meditation" could be ascribed to any of the traditions tied to Celtic traditions. That is to say, while there are things that in modern understandings could be considered meditations- I am not sure the Celts in the time of the Druids would identify them as such. I could be mistaken- and indeed, they may have had a tradition that is similar to meditation.
I'm not sure "respect for nature" translates as well. I mean, I am sure they respected the sheer force and devastation the elements could bring- what agrarian society didn't? But I have a sinking suspicion that what we call "respect" and what they called respect for nature wouldn't translate into modern pagan practices the same way. I mean, it wasn't like the Celts didn't offer blood sacrifices for the field.
Really- I think they were more concerned with respecting their gods and dealing with the otherlings that could effect their wellbeing.
The common idea of respecting nature isn't uncommon amongst Eclectic Neo-Pagans though.
Magic is a completely different story all together. While we are pretty sure that there were Druid mystics, being a Druid didn't make you a mystic unto itself. There were mound builders, story tellers, law givers- a host of professions under the title of Druid.
Interestingly enough, the actual magical disciplines of the Celts isn't a popular topic.
Did you know that Eclectic Neo-Paganism has a host of magical traditions that are as varied as the people who consider themselves Eclectic Neo-Pagans? It opens up the possibility for people to find a style that suits them within the bounds of ethical cultural appropriation and personal creativity.
