Moon

What this is

The Moon is the light that has no light of her own, the mirror that gives the Sun back softened and changed. She is the nearest and swiftest of the wandering lights, and because she changes shape night by night she became the measure of the month and the figure of all that waxes and wanes. On the Tree she is Yesod, the lunar foundation just above the world of matter, where every form must pass before it can take flesh.

What it governs

She rules Monday — the moon's day, plain in the very name — and the planetary hours that carry her keynote through the week. Her sphere is Yesod, Foundation; her sign is Cancer; her element is water. In a life she governs the body's tides, sleep and dream, memory and the unconscious, the mother and the home, psychic perception, and everything that moves in cycles rather than straight lines.

Its properties

Her colour is silver and pale blue, her metal silver, her stones moonstone, pearl, and clear crystal; her number is nine, drawn from the largest of the seven kameas, the 9×9 square. The incense is camphor, jasmine, and myrrh, the plants willow, lotus, mugwort, and white rose. Upright she is intuition, tenderness, the deep memory that holds a people together, the dream that shows you what daylight hides. Her shadow is Hasmodai, the tide that drowns — illusion, emotional flooding, the lunatic state, the dream that captures you instead of teaching.

Where else it appears

Selene drives her chariot for the Greeks, and beside her stand Artemis of the new moon and Hekate at the dark of it, three faces of one light. Egypt gives her Isis, mistress of magic and mourning; the Celts feel her in Ceridwen at her cauldron of transformation. On the Tree she is Yesod, the treasure-house of images, where Gabriel stands in the place of water in the West — the same Gabriel of dream and annunciation. Pour a libation to Hekate at the crossroads or set a bowl of water out to scry under the full moon: it is one reaching toward one tide, and the hermetic word for it is Rhythm, the ebb and flow in all things.

Where you meet it on the Oracle

The Moon shares the spine with the Sun, and on The Day surface she rules Monday outright — the whole reading of that day bends to her water. She also recurs as a planetary hour through every weekday, and when her hour opens it marks a window for the inward work: dreaming, resting, listening, scrying, anything done by feel rather than force. When the Moon rises in your reading, take it as permission to go soft and slow, to trust the gut, to tend the body and the home, and to let a thing change rather than holding it fixed.

Why it matters

She is so because nothing alive grows in a straight line; everything that matters comes and goes in tides, and the Moon is the teacher of that rhythm. She matters because a person who cannot ebb cannot flow either, and the inner life starves when only the daylight will is fed. What she asks is that you make room for the dark of the cycle as well as the full — that you let yourself receive, and rest, and dream.
