Mithuna is the air sign symbolised by the twins, ruled by Mercury (Budha). A Mithuna Moon is traditionally read as a mind that processes feelings by talking and thinking them through. Conversation, reading and learning something new tend to settle you.
Work: Often thrives in communication, writing, teaching, sales, media, technology and any role that rewards quick learning.
Relationships: Needs a partner who is also a friend and conversation companion; boredom is a bigger risk than conflict.
