I see the ritual as a means of opening the channels of perception and unleashing creative potential, as well as one of eradicating blockages - a way of allowing oneself to see what needs to be seen, whether or not it is something that one desires to see. Realignment.
The pomegranate contains many seeds, all encompassed within a skin. By breaking the skin and releasing juice, the divisions between seeds are destroyed. There is an intermingling. This intermingling can be seen as representative of eradicating divisions between human beings, connecting pieces of a disjointed picture, or anything else along the lines of creating unity or understanding. Closely resembling blood, the juice can be lifeforce, and conversely, the pain of letting go - transformation and release.
One way of looking at it, anyhow...
I think we have the beginnings of some fertile and workable plans for the Equinox. As I understand it thus far we have:
Pomegranates to "sacrifice" or open
(we will need a ceremonial blade)
The chalice we will drain it into.
Do we want to free form the ceremony so that each person says what it means individually? I think this would be good, then at the end, after each person has done their own energy drawing, the chalice is passed to share that amongst the group.
Perhaps given that most of us (digitalsidhe possibly excepted) feel the Autumn as more of a time of personal rebirth rather than "death" we might want to work that sense of darker passge into something brighter into the Work. With my current Anubis thing, the immediate thought is something to the effect of guidance through the darkness of Amenta, where there is only oneself to rely on, to the joining of our individual brightness with others. It might be straying afield from the original energy drawing concept, but I also believe that concern over losing feelings of connectedness was also an issue for us. Thus we gain individual energy from our connection with each other.
