Neidan — Inner Alchemy Microcosmic Circuit

Ren Mai (Conception Vessel): Runs up the front of the body from perineum to lips

• Associated with yin, receptivity, water element
• Seven energy centers (dantian): lower abdomen, solar plexus, heart, throat, third eye, crown

Du Mai (Governing Vessel): Runs up the back from perineum to crown to palate

• Associated with yang, activity, fire element
• Eight energy centers: perineum, lower back, kidney, heart, neck, head centers

Activation:

• Begins with lower dantian cultivation (heat and power)
• Energy ascends the spine through du mai
• Reaches the crown and pineal/pituitary (jade pillow, niwan)
• Descends the front through ren mai
• Returns to lower dantian, completing the circuit

Effects:

• Enhanced vitality and longevity
• Awakening of subtle perceptions
• Emotional equilibrium
• Clarified consciousness
• Refined energy bodies

Meditation approach:

• Sitting in inner alchemy posture (half-lotus recommended)
• Circulate energy through breath coordination
• Visualization of energy flowing the pathway
• Accumulation at lower dantian, middle dantian, upper dantian

Movement approach:

• Taiji and qigong forms encode the circuit
• Movement naturally guides energy through the pathways
• Martial arts develop the circuit explosively

The microcosmic circuit is safe when practiced properly but can cause problems:

• Excessive heat in the head (practicing without grounding)
• Psychological instability (energy moving faster than consciousness develops)
• Sexual dysfunction (misunderstanding of sexual practices)

• Months: Warmth, vitality, improved sleep
• Years: Emotional stability, spiritual perception, energy control
• Decades: Complete transformation, spiritual attainment
