Around 1995, I came up with the idea of a ritual with two chalices, to represent same-sex love. The idea of having two cups also resonates nicely with the Temperance card in the Tarot.
Later, when actually doing this ritual, we realised that the cups could be passed around the circle so that everyone can take part.
How to do it
You have person A, B, C, D, E standing in a circle.
A passes empty cup 2 to B. A pours full cup 1 into empty cup 2 & says “I fill your cup with love”.
Then A passes empty cup 1 to C. B then pours full cup 2 into empty cup 1, being held by C. And so on.
