The essence
The Moon has no light of her own. She reflects the Sun's light back to Earth, and astrologers read that reflection as your receptive side: how you take in the world, how you react before you have time to think, how you care for yourself and others. She rules Cancer, the sign of the shell and the hearth. She is exalted in Taurus, where needs become physical and are met through food, rest, and touch. She is in detriment in Capricorn and in fall in Scorpio, signs where feeling has to work harder to show itself.
The Greeks knew her as Selene, who drove her chariot across the night sky, and linked her with Artemis and Hecate, goddesses of the wild places and the crossroads. Her monthly cycle, from new to full and back again, gave many early cultures their first calendar. She changes not because she is fickle but because she is alive to what is, a steady reminder that nothing stays and everything returns.
Your Moon's sign and house show the emotional climate you grew up in and the one you tend to recreate. It is the part of the chart that does not perform. It simply is.
