In Taoist sexual kung fu, the Plain Girl, Rainbow Girl, and Mysterious Girl describe stages of feminine (yin) energy within all bodies. Each has a masculine (yang) counterpart and connects to a chakra and dantian—moving from Jing to Chi to Shen, or body to heart to spirit.
Plain Girl ↔ Pure Boy
Chakras: Root & Sacral
Dantian: Lower
Element: Earth
Plain Girl represents raw, physical, instinctual desire—the foundation of life-force (jing).
Pure Boy brings grounded presence and containment, the discipline that channels desire.
Together they build strength, stability, and vitality.

Integration
Everyone holds these yin and yang forces within.
Yin offers softness, receptivity, and transformation.
Yang offers structure, focus, and direction.
When both are balanced, sexual energy becomes a current that rises from grounded vitality to openhearted love to awakened spirit.
