To begin with this is my own program of study, it is not associated with anyone and I came up with it based on a few things I read across the Internet in different and scattered places as well as advice from some friends. I’m sure that some will think it is too much, while others will think it is a load of hogwash. Follow it or don’t, it is totally up to you. I’m also including A Starter’s Kit of books at the end for people who want to give it a try but don’t want to invest too much time and money in the beginning to find out whether this is for them or not.
Get a sense of geography; figure out where everything was and is in Europe. History is next; you need to have a look at the history of Europe in general and then the Indo-Europeans, Greeks, Romans as well as the Celts. The reason for this is that all of these cultures impacted on the Celts in one sense or another.
You then need to study the culture and history of Ireland. You might want to study the language too, as this can be a great way to look at the culture.
You’ll want to look at Celtic mythology and folklore as well as comparative mythology from other cultures related to the Celts.
Learn about magic, trance work, meditation and divination through practical involvement. Again, many of the actual patterns and techniques are cross-cultural. Understanding the dynamics involved through personal experience will help you apply that knowledge to the specifically Celtic forms you will find in the sources.
Some books to aid you:
1. Europe: You need to have a working knowledge of European history as well as the Indo-Europeans. The European history will help you put into perspective who the players that may have affected the Irish Celts and where everyone was at any particular time in history.
