The Progressed Moon represents your current needs, relationships, and general emotional state. When your PR Moon sign or house changes, your needs evolve, and the shift from Taurus to Gemini or 2nd house to 3rd house shakes you up. You have new curiosity about your immediate environment. You switch from needing security to needing information. You are entering a period of communication (about 2.5 years for the Gemini progression, 1-4 years for the natal 3rd house progression, depending on its size).
Gemini is the third Zodiac sign, the school child who has left the security of home to learn. As an Air sign, Gemini needs social interaction, and when your PR Moon leaves Taurus or H2 and enters Gemini or H3, you become fascinated with the world. Gemini excels at reading, writing, and speaking, and this progression is a great time to take courses on information technology, English, foreign language, creative writing, poetry, social media, computer science, etc. Gemini is very dextrous, so now is a great time to learn things involving your hands: knitting, pottery, calligraphy, musical instruments, etc.
Taurus and Gemini are different energies. Taurus is ruled by Venus, focused on material things. Gemini is ruled by Mercury, the planet of information and communication. Taurus is subjective, Gemini is objective. During this progression, you’ll seek out people who are talkative and flexible. Gemini is a Mutable sign (and H3 a “Cadent house”) representing the change from Spring to Summer, so you become more adaptable and comfortable with change. You’ll want to get out of the house, talk to the neighbors, see what’s going on in your community, and take more short trips.
When PR Moon is in Gemini/H3, you can become too superficial. Gemini, like all Air signs, can lack emotion and empathy. Your need for light conversation can lead to gossip, which hurts people more sensitive than yourself. Gemini has a cruel streak, including mockery and mimic just for a few laughs, and has issues telling the truth, which is an abstract concept. Once you’re caught in a few lies, people don’t trust you, no matter how harmlessly they were meant. You’ll also need to be aware of developing attention deficit, mental illness, and nervous issues.
The Gemini lunar progression is easiest for people with natal Moon in an Air sign (Gemini, Libra, Aquarius), and most challenging for those with natal Moon in another Mutable sign (Virgo, Sagittarius, Pisces). The 3rd house progression is a time of wanting to communicate, with a special emphasis on sibling/neighborhood relationships, writing, and entering into written contracts.
