I'm going to try and address your question, but I may not hit the mark you are seeking. If not, I apologize - but maybe you'll find something here to help you out.

The first problem for most folks who are drawn not only to The Morrighan but to the other Celtic deities is that (at least as far as I've been able to find out) the height of their active worship by the Celtic peoples - wasn't recorded in any permanent manner. In other words, again as far as I've been able to discover, while there are stones found in Ireland with carvings and sometimes "writing" much of the time it translates into boundary markers between two farms or the equivalent of shopping lists and what not. My suspicion is that whatever the relationship the Celts had with their deities it was passed down by word of mouth and at this remove with the intervening years of conversion to Christianity much if not perhaps all of the original "ways of worship" aren't recoverable.

The information I have is often from texts that are essentially built upon what sketchy archaeological info we have and educated guesses. One wonderful source that is extensive and as complete as the authors could make it is Martha Ann and Dorothy IMers Myer's *Goddesses in World Mythology.* It's essentially a biographical dictionary and covers every continent. You may have to really look for this book because I think it's out of print.

So, the way I've approached this particular hurdle is to honestly follow my instincts. My own personal practice I wouldn't classify as "worship" because for me that conjures up images of going to church when I was a kid and such tightly scripted ritual makes me cranky. BUT that's me and other folks need something else.

I suggest you find a time when you will be uninterrupted, quietly enter into the meditative state that works best for you and let Her tell you what She wants. Trust that you have a connection with Her and that She will tell you what She wants you to know.

As for incense - I've found these suggestions in a variety of sources: frankincense, myrrh (probably because classically these are herbs and resins associated with Death and Deity), holly, juniper, and ivy (the last three I suspect because when most of us think of the Celts we think of the British Isles and Ireland especially and these plants are common there.

In my own practice my altar is a working altar and not Deity specific. What is absolutely specific to The Morrighan is my first tattoo. I came out of a trance state still feeling the skin burn where she branded me with it. I was able to render it fairly well and find a tattoo artist who understood what I needed.

I hope in here there's something to help you out. Good luck.

Peace,
