The internal discipline of Sōng (Release, 鬆) in Taijiquan transcends mere anatomy; it is a profound neurological and psychological achievement. For the master, the critical challenge is not achieving Sōng in stillness, but maintaining it under the chaos of pressure. This is Relational Sōng (Jiāoshǒu Sōng, 交手鬆), and its perfection leads to the instantaneous state of optimal readiness known as the Zero Point (Líng Diǎn, 零點).
True Sōng is a state where the practitioner has achieved Neurological Quietude—the conscious suppression of the instinctual bracing reflex that hinders the flow of Internal Power (Jìn, 勁) and the efficacy of Intent (Yì, 意).
The Problem of Reactionary Tension: Under force, the untrained nervous system instantly engages Brute Force (Lì, 力) by tightening superficial musculature (chest, shoulders, neck). Sōng is the result of years of mental training (Sinking the mind) that allows the Mind/Spirit (Shén, 神) to maintain a detached, alert tranquility.
The Unity of Intent (Yì, 意) and Sōng (鬆): Intent guides Vital Energy (Qì, 氣), and Sōng is the clear, open pathway through which Qì can flow. Neurological Quietude is therefore the foundation for the Unity of Mind and Spirit (Xīn Shén Hé Yī, 心神合一).
The ability to Listen to Force (Tīng Jìn, 聽勁) is the ultimate test of Sōng's sensitivity.
The Ear of the Skin: Tīng Jìn is primarily a tactile and proprioceptive skill enabled by profound Sōng. When the fascia and joints are truly released, they become highly sensitive, acting as a massive single sensor. The slightest change in the opponent's center of gravity or intent is instantly registered.
Adherence and Connection (Zhān Nián Lián Suí): The principles of Sticking (Zhān, 粘), Adhering (Nián, 黏), Connecting (Lián, 連), and Following (Suí, 隨) are all dependent on Sōng. The relaxed structure allows you to immediately match the opponent's pressure without either collapse or resistance, ensuring your structure remains intact while dismantling theirs.
The Zero Point (Líng Diǎn) is the pinnacle of dynamic Sōng, representing the instantaneous state where an incoming force is met, equalized, and harmonized. It is not a place of action or inaction, but a precise moment of absolute energetic and structural equilibrium achieved just before one chooses a counter-response.
The Líng Diǎn is the infinitesimally small moment in which the body achieves total stillness across three dimensions:
Force: The body neither resists (kàng 抗) the opponent's force nor completely yields to it.
Space: The center does not retreat, nor does it press forward.
Time: The moment is outside of conscious reaction, allowing for instantaneous processing.
This total stillness defines the moment of maximum Emptiness (Xū, 虛) and maximum readiness, where the Waist (Yāo, 腰) and Energy Center (Dāntián, 丹田) are perfectly aligned.
The Líng Diǎn can be considered the moment of ultimate Neutralization (Huà Jìn), as it completely dissolves the opponent's intent, structure, and power. In this state, everything the opponent attempts to do comes back at him—his own effort creates his undoing and demise.
From the foundation of the Líng Diǎn, all martial possibilities are instantly unlocked:
Capturing Power (Nà Jìn 拿勁): The opponent's force is seized and manipulated.
Issuing Power (Fā Jìn 發勁): The explosive power is released from a state of total neutrality.
Redirecting Power: The force is channeled around or back to the opponent.
Mastery of the Zero Point transforms the body into a perfect elastic structure, instantly ready to receive, store, and return force without conscious deliberation.
The attainment of Neurological Quietude through Sōng (Relax, 鬆) is the mechanism by which the Master's Mind (Shén, 神) fuses with the Rooted Structure (Gēn, 根). This fusion allows the practitioner to navigate the dynamic chaos of interaction by maintaining the absolute tranquility of the Zero Point (Líng Diǎn, 零點), fulfilling the highest martial principles of Taijiquan.
