Yi (意, intention), Song (鬆, relaxation), and Jin (勁, refined force transmission).

 Yi (意, intention), Song (鬆, relaxation), and Jin (勁, refined force transmission). 

The concepts involved include:

1. Redirecting Attention to the Ground or Sole
• When your mind connects to the ground, you establish a downward energetic connection (根, root), making it harder for someone to lift you.
• This utilizes gravity and ground connection to maintain stability.
• If the foot is relaxed properly, the force doesn't get "hooked" at the leg but flows downward.
2. Extending the Mind to a Distant Point (Front Wall, etc.)
• When the mind extends forward, the body's internal force aligns in that direction, distributing the pull's effect across the structure rather than isolating it in the leg.
• This follows Yi Dao, Qi Dao (意到氣到, where the mind leads, energy follows).
• The opponent’s force is diffused rather than resisted.

Other Similar Examples

1. Rooting Against a Push (Sinking and Expanding)
• When pushed on the chest, instead of resisting or collapsing, you can either:
• Relax and sink into the ground (重心下降, lowering center of gravity).
• Expand intention outward (如同氣球, like an inflated balloon).
• The push gets absorbed or redirected rather than knocking you over.
2. Softening an Arm Grab (Emptying the Point of Contact)
• If someone grabs your wrist, instead of tensing up, you relax the wrist and mentally extend forward.
• The grip often loses effectiveness because there's no fixed resistance to latch onto.
3. Unliftable Shoulder (Peng Energy)
• If someone tries to lift your shoulder, instead of resisting downward, you expand Peng (掤) upward and outward.
• This makes the shoulder feel heavy and unmovable.
4. Lightness in Jumping (Intent to the Head)
• If you focus attention on the top of the head (百會 Baihui point) while jumping, it creates a sensation of lightness and makes the jump easier.
5. Absorbing Force into the Kua (Hip Fold)
• If someone pushes against your torso, you relax and absorb the force into the kua (胯), allowing energy to pass through rather than resisting.
• This follows four ounces moving a thousand pounds (四兩撥千斤).
6. Using Spiral Energy to Neutralize Lifting
• If someone tries to lift your arm, spiraling the arm (纏絲勁, Silk Reeling Energy) downward or outward disperses the force, making it hard to lift.
7. Unbendable Arm through Expansion
• Instead of stiffening to resist someone bending your arm, expanding intent outward while maintaining relaxation makes it resilient yet unbendable.

Core Principle Behind All These Examples

• Mind Leads Energy (意領氣行, Yi Ling Qi Xing)
  Your intention directs where force flows.
• Relaxation without Collapse (鬆而不散)
  Proper relaxation allows energy to transmit smoothly rather than be blocked.
• Structure and Connectivity (整體勁)
  The whole body works as a unit instead of isolated parts resisting force.

This is a fundamental principle in Tai Chi. The concept is called "song" (松) or "fangsong" (放松), which translates to relaxation or letting go. When you are pulled up by the leg, you relax the place you are held and either put your attention to the ground or sole and relax the foot, or your mind connect with the wall in front of you, your leg can hardly be pulled up. This is because when you relax, your body becomes more pliable and yielding, making it harder for the attacker to gain leverage.

Here are some other examples of how "song" is applied in Tai Chi:

• When you are pushed, you relax your body and let the force of the push pass through you. ¹ This is similar to how a willow tree bends in the wind but does not break.  1. 'Testing' Postures  Taiji

• When you are grabbed, you relax your muscles and let the attacker's grip loosen. This is because when you are relaxed, your body is not as rigid and easy to hold onto.
• When you are struck, you relax your body and let the force of the strike dissipate. This is because when you are relaxed, your body is not as tense and likely to be injured.

In all of these examples, the principle of "song" is used to neutralize the attacker's force and make it difficult for them to gain an advantage. This is why Tai Chi is often described as a "soft" martial art.

Here are some other examples of how the principle of "song" can be applied in everyday life:

• When you are stressed, you can relax your body and mind to reduce the tension. This can be done through deep breathing, meditation, or yoga.
• When you are angry, you can relax your muscles to prevent yourself from lashing out. This can help you to stay calm and in control of your emotions.
• When you are in pain, you can relax the affected area to reduce the discomfort. This can help to promote healing and reduce inflammation.

By practicing the principle of "song" in Tai Chi, you can learn to apply it to all aspects of your life. This can help you to reduce stress, improve your health, and enhance your overall wellbeing.

The phenomenon is rooted in the principles of Tai Chi (太極) and Qigong (氣功), particularly the concepts of relaxation (鬆, Sōng), rooting (根, Gēn), and mindbody connection (心身合一, Xīn Shēn Hé Yī). When you are pulled up by the leg, the ability to remain grounded and resist being lifted is a demonstration of internal energy (內勁, Nèi Jìn) and proper alignment. Below, we’ll explore the theories behind this, provide examples, and explain how it works.   

Theories Behind the Phenomenon 

1. Relaxation (鬆, Sōng):  By relaxing the area being held (e.g., the leg), you avoid creating tension that the opponent can exploit.  Relaxation allows energy to flow freely and prevents the opponent from finding a point of resistance. 

2. Rooting (根, Gēn):  Rooting involves creating a strong connection to the ground through the soles of the feet (腳底, Jiǎo Dǐ).  When your mind focuses on the ground or the soles of your feet, you enhance this connection, making it difficult for the opponent to lift you. 

3. MindBody Connection (心身合一, Xīn Shēn Hé Yī):  By mentally connecting with the ground or an external object (e.g., a wall), you create a sense of stability and immovability.  This mental focus aligns your body’s energy and structure, making it harder for the opponent to disrupt your balance. 

4. Energy Flow (氣, Qì):  Proper energy flow ensures that your body acts as a unified system. When one part is pulled, the energy is redirected through the body and into the ground, neutralizing the force.   

Examples of Similar Principles in Tai Chi Here are several examples where these principles are applied:  

1. Resisting a Push (抗推, Kàng Tuī):  

Scenario: An opponent pushes your chest or shoulders.  Application: Relax the area being pushed, focus on rooting through the feet, and mentally connect with the ground. The force is absorbed and redirected into the ground, making it difficult for the opponent to move you. 

2. Neutralizing a Pull (化拉, Huà Lā):  

Scenario: An opponent pulls your arm.  Application: Relax the arm and shoulder, focus on the soles of your feet, and allow the force to flow through your body into the ground. This neutralizes the pull and maintains your balance.  

3. Resisting a Lift (抗舉, Kàng Jǔ):  

Scenario: An opponent tries to lift you by grabbing your waist or legs.  Application: Relax the area being held, focus on the ground, and mentally connect with a stable object (e.g., a wall). This creates a sense of immovability, making it difficult for the opponent to lift you. 

4. Neutralizing a Twist (化扭, Huà Niǔ):  

Scenario: An opponent twists your arm or body.  Application: Relax the affected area, focus on the soles of your feet, and allow the force to spiral through your body into the ground. This neutralizes the twist and maintains your structure.  

5. Resisting a Shoulder Strike (抗靠, Kàng Kào):  

Scenario: An opponent leans into you with a shoulder strike.  Application: Relax the area of contact, focus on rooting, and mentally connect with the ground. The force is absorbed and redirected, making it difficult for the opponent to destabilize you.   

Additional Examples of Rooting and Neutralizing 

1. Standing Meditation (站樁, Zhàn Zhuāng):  In standing meditation, practitioners focus on rooting and relaxation to develop internal strength and stability. This practice enhances the ability to resist external forces. 

2. Tai Chi Walking (太極步, Tàijí Bù):  During Tai Chi walking, practitioners maintain a strong connection to the ground while moving. This develops the ability to remain rooted even in motion. 

3. Push Hands (推手, Tuī Shǒu):  In Push Hands, practitioners use rooting and relaxation to neutralize their partner’s force. This develops sensitivity and the ability to redirect energy. 

4. Single Leg Stance (獨立步, Dúlì Bù):  Balancing on one leg while maintaining relaxation and rooting demonstrates the principles of stability and immovability.   

Conclusion The ability to resist being pulled or lifted in Tai Chi is a result of relaxation, rooting, and mindbody connection. By focusing on the ground, mentally connecting with a stable object, and maintaining proper alignment, you can neutralize external forces and remain balanced. These principles are applied in various Tai Chi practices, such as Push Hands, standing meditation, and Tai Chi walking, and are essential for developing internal strength and stability.

Tai Chi (太極) and Qigong (氣功), particularly the concepts of relaxation (鬆, Sōng), rooting (根, Gēn), and mindbody connection (心身合一, Xīn Shēn Hé Yī). When you are pulled up by the leg, the ability to remain grounded and resist being lifted is a demonstration of internal energy (內勁, Nèi Jìn) and proper alignment. Below, we’ll explore the theories behind this, provide examples, and explain how it works.

 Summary

1. Focus on the Ground (腳底, Jiǎo Dǐ):

    When pulled or pushed, direct your attention to the soles of your feet and imagine roots extending into the ground. This enhances your connection to the earth and makes you feel heavier and more stable.

2. Mentally Connect with an External Object:

    If you are near a wall or another stable object, mentally connect with it. Imagine your body extending into the object, creating a sense of immovability.

3. Relax the Affected Area:

    Relax the part of your body being held or pulled. Tension creates resistance, which the opponent can exploit. Relaxation allows energy to flow and neutralizes the force.

4. Use Circular Movements (圓, Yuán):

    If the opponent’s force is too strong, use circular or spiral movements to redirect the energy. This aligns with the principle of neutralizing force (化勁, Huà Jìn).

5. Maintain Proper Alignment (對齊, Duì Qí):

    Keep your body aligned from the crown of your head to the soles of your feet. Proper alignment ensures that energy flows smoothly and that you remain balanced.
