Why the “twins” matter: a clear Gemini reading

Gemini’s mythic twins, one mortal and one immortal, capture the tension between our human needs and our soul aims. Under this lunation, treat both with respect: feed the body, then feed the story you are writing with your life. Wikipédia

Signal to practice:

• Human side: rest, food, a boundary you will keep.
• Soul side: curiosity, conversation, a single brave truth spoken.

Moroccan note, simplified for U.S. readers: In Maghrebi stargazing circles, storytellers often use the twins to talk about everyday survival alongside purpose. Same moon, same lesson: balance, then move.

woven in: build like an RPG dual-class

Gamers, think of this full moon as a dual-class respec:

• Class 1, “Human”: HP, shelter, calendar hygiene.
• Class 2, “Soul”: quests that spark joy, not just XP.
  Pick one utility skill (sleep, water, walk) and one signature skill (reach out, draft the pitch, ship the portfolio page). Lock them in for 7 days.

“Heated” feelings without the hype

You may feel amped because supermoons look brighter, social feeds get louder, and Gemini invites dialogue. That said, Mars is not retrograde in December 2025. Mars ended its retrograde earlier in the year, so treat any heat as normal human emotion, not cosmic punishment. horoscopes.astro-seek.com+1

Skill up:

• Name the feeling.
• Put it in a container: 10 pushups, a walk, a voice memo, or one honest boundary.
• Repair if needed, but do not disown a truth you meant.
