I had an inspiration for a variation on the standard three card reading today. Rather than reading the positions as, say, Past, Present, Future, or, Maiden, Mother, Crone, one could string them together as if in a sentence: Subject, Verb, Object.
I tried this with my deck and came up with some interesting results:
Uma, Erzulie, White Tara: Loss desires compassion.
Oya, Gaea, al-'Uzza: Change grows from strife.
Hel, Aida-Wedo, the Virgin Mary: Balance encompasses wonder.
Gwenhwyfer, Danu, Sibyl: Beauty thrives on mystery.
Athene, Sophia, Tlazolteotl: Wisdom knows temptation.
Faerie, Ganga, Inanna: The seasons dance seductively.
Laverna, Sif, Sunna: Time thieves beauty and glory.
Ho Hsien-Ku, Kali, Isis: Openness destroys sorrow.
The Cailleach, Nut, Pomona: Every winter is pregnant with autumn.
Sengen, Chalchiuhtlicue, Kelaeno: Water and wind will wear down the mountain.
These were all off-the-cuff, saying pretty much the first thing to come to mind; it would be interesting to take the same three cards and see how many different sentences you could come up with. You could also switch them around into different positions to explore their meanings further.
I am definitely a fan of the Mary Greer method of exhausting a reading by combining and recombining the cards in as many ways as you can come up with. It's a good way to get to the depths of the thing.
