I think, perhaps my understanding of paganism is a bit outdated. The religions of Socrates' time come to mind. From what I understand of witches--and I'm sure it's more likely a misunderstanding--they somehow worship nature and for them casting spells is more like a prayer. Forgive my ignorance and please try not to laugh as you correct me!
You could more or less characterize it that way, though as a simplification, it has its inaccuracies. There is Witchcraft and witchcraft - I put it in proper case like that to designate I'm talking about a religious approach, not simply a practice of spellcraft. If we're referencing simply a practice of spellcraft, then witchcraft (lower case) doesn't involve any sort of worship and can be atheistic. But in terms of being a contemporary religious movement, it'll tend to involve "folksy" or "naturey" stuff, which may or may not be accurately characterized as "nature worship." It might be better to say that various aspects of the world called "nature" are viewed as partners and equals, where they might be honored and revered (aka, worshiped), but might not be. Depends on the practitioner. As for spellcraft being like prayer, it's presented that way mostly to help outsiders (usually Christian or with a Christian background) to understand. There's a critical difference between the two: prayer is a passive "fix it for me, God" sort of thing. Spellcraft is very much the opposite - it is an active "I am a creature of power and taking charge of my own life." One don't expect hand outs or a free lunch, I guess.
so would you say not holding a grudge is pretty much all forgiving is?
In terms of the function it holds for the person doing the forgiving, that's what makes sense to me at this present moment. Often, but not always, there's the other facets of it, though. The term "forgiveness" is typically relational. There's an object of forgiveness, and a relationship between the two or more objects as well. Words like "grudge" might not characterize those other facets.
