先天氣，內氣，元氣

先天氣，內氣，元氣

They’re related concepts in Chinese internal cultivation, but they’re not the same — the differences mainly come from how classical Daoist, TCM (Traditional Chinese Medicine), and martial arts lineages define “qi” at different stages or origins.

Here’s a careful breakdown:

---

1. 先天氣 (Xiān Tiān Qì — Pre-Heaven Qi)

• Meaning:
  “Pre-heaven” refers to what you are born with — your innate life force, inherited from your parents at conception.
  In TCM, it is stored in the Kidneys (腎) as Jing (精) and is the root vitality of your life.
  It determines your constitution, potential longevity, and basic resilience.

• Characteristics:

  • Cannot be directly “replenished” — once exhausted, life ends.

  • However, it can be conserved and nourished by reducing unnecessary depletion.

• Cultivation focus:

  • Gentle lifestyle, quality sleep, balanced emotions.

  • Avoid overwork, excessive sexual activity, or chronic stress (which burn Jing).

  • Deep, slow breathing to minimize energy leakage.

  • Some advanced Daoist methods (e.g., reverse breathing + dantian refinement) aim to “convert post-heaven qi into pre-heaven essence,” but this is considered high-level.

2. 內氣 (Nèi Qì — Internal Qi)

• Meaning:
  This is the functional, circulating qi inside your body — the energy that moves in the meridians, animates organs, powers movement, and responds to your intent (意).
  In martial arts, this is the “internal power” you cultivate through body-mind integration.

• Characteristics:

  • More immediately accessible than pre-heaven qi.

  • Can be increased and regulated through training.

• Cultivation focus:

  • Tai Chi, Qigong, Dao Yin to coordinate breath and movement.

  • Use mind-intent (意) to guide qi circulation, e.g., from dantian to limbs.

  • Maintain song (鬆, relaxed) and chen (沉, sinking) in posture.

3. 元氣 (Yuán Qì — Original Qi / Primordial Qi)

• Meaning:
  The source energy that drives all physiological functions — formed from the fusion of pre-heaven essence (from your parents) and post-heaven qi (from food, air, environment).
  It resides between the kidneys (命門) and is the “battery” for life activities.

• Characteristics:

  • Acts as the mediator — when you use internal qi, you’re drawing on and supported by yuan qi.

  • Can be replenished slowly via healthy living, but depletion over time is natural.

• Cultivation focus:

  • Nourish with good nutrition (post-heaven qi source).

  • Strengthen kidney function (jing storage).

  • Gentle qigong, meditation, standing practice to consolidate qi in lower dantian.

Relationship in Simple Form:

先天氣  (Pre-Heaven Qi)  →  元氣 (Original Qi)  →  內氣 (Internal Qi in use)
   |           |                    |
   |           |                    → used in movement, healing, martial arts
   |           → supported by post-heaven sources
   → root vitality, inherited

• 先天氣 is your inherited capital.

• 元氣 is the bank account you draw from daily.

• 內氣 is the spending money in your pocket — the part you can actively circulate and train.

Practical Cultivation Roadmap

1. Preserve 先天氣:

   • Avoid over-strain, over-thinking, and reckless lifestyle habits.

   • Gentle, restorative qigong rather than harsh or explosive training at the beginning.

2. Replenish 元氣:

   • Eat fresh, balanced, whole foods.

   • Breathe deeply and naturally, spend time in nature (clean air = better post-heaven qi).

   • Maintain kidney health (warm lower back, avoid chronic cold exposure).

3. Refine 內氣:

   • Practice Tai Chi, standing meditation, silk-reeling exercises.

   • Coordinate mind, breath, and body to gather qi into the lower dantian, then circulate.
