Draw a circle, with salt, widdershins. Place an earthenware pot, filled with water, center circle. No fire necessary. Hyacinth incense is nice, but not really necessary. Think all things "water" to create your center altar. Crystals...white willow branches, kelp & seashells, etc.
You will either need a drummer, or a decent rattle. Start by chanting, keeping time with drum or rattle. Let the rhythm go down to your feet. Begin to dance, as you feel the mood strike you. Then circle, deosil...in opposition of the circle drawn, in order to reverse the elements. Proceed until you feel a sense of release. Tears are helpful, but only if they occur as a natural result of the ceremony.
Then? Sacrifice a cactus.
