Gate Cards in the Rider Waite Smith

Gate Cards as explored by Rachel Pollock make for interesting mediations. In her book, Seventy-eight Degrees of Wisdom we find the following cards mentioned as gate cards: 8 of Cups, 6 of Swords, 10 of Pentacles, 6 of Pentacles, 3 of Wands, 5 of Cups, 5 of Cups and Ace of Cups. According to Rachel, these cards bring awareness and helps us produce such awareness, by way of experiences that reach beyond the cards.
Bring Rachel's book if you have it and of course a deck. Let's see which gate(s) open for us.
