True Meaning of Bā Jìn 八勁 – Eight Jìn
Péng is expanding and Lǚ is contracting. They can be in the six other Jìn, for example Àn Jìn can be Péng or Lǚ, so it can be Péng Àn Jìn 掤按勁 or Lǚ Àn Jìn 履按勁. Likewise, Cǎi can be Péng or Lǚ, so it can be Péng Cǎi Jìn 掤採勁 or Lǚ Cǎi Jìn 履採勁. Whether we use Péng Jìn or Lǚ Jìn, they must also follow the principles of Chán Sī Jìn 纏絲勁 – Silk Reeling Energy. An outwards circle is Shùn 順 and an inwards circle is Nì 逆. When we practise Tàijíquán 太極拳 the spiral must come from the Dāntián 丹田 and spiral out to all parts of the body, and then to the opponent, when we are striking or attacking another way. During Tuī Shǒu 推手 – Pushing Hands, we apply the Bā Jìn which we can clearly see. When we practise the form and follow the Chán Sī Jìn and from here we will discover where Péng and Lǚ are in the movement, and then we will find where the other six Jìn can be found. Just practise each movement and follow the principles and Chán Sī Jìn and the Bā Jìn will happen along the way.
