The Quarter Days mark the beginnings of the seasonal changes, and the Cross Quarter Days mark the midpoints. Jus' Bobbin' Along. . . There is a traditional activity associated with Halloween that can be a very effective ceremonial tool at Samhain. It's bobbing for apples. This is an age old tool for communicating with the other side.
Water represents that veil that is so thin at that time.
Apples have always been associated with Goddess and temptation. Let me tempt you if I may with a technique that might yield some interesting results. At your Samhain gathering, have a big bucket or cauldron, some room temperature water, and a number of largish apples. Before you begin, you need to have a question. Pick something that is happening for you at that moment that you relate with Samhain - perhaps some part of your life that is over, or another area where you need to sow some new seeds.
