If there is any single "real" meaning of Easter, it is simply a celebration of life and the fertility of the earth, the renewal of things. Looking at the linguistic etymology, it is probably the celebration of a particular ancient Germanic goddess, a Germanic form of the proto-indo-european goddess of the dawn.

But that's not that important in and of itself. Mainly what I want to say is, before you go around talking about celebrating the "real" meaning of some holiday or tradition, think about whether there really is any single "real" meaning in an objective sense, or simply the meaning that you have ascribed to it for yourself. There is no problem with ascribing your own meaning to an event or tradition, in fact, it's probably a good thing. But to then go around parading that as the "real" meaning is a bit arrogant, I feel.
