Introduction to the Concepts of Yi/Intent and Xin/Heart-Mind, in Chinese Martial Arts

Many people think that martial arts are a way to improve physical fitness and develop the ability to defend oneself. These are merely physical aspects with tangible boundaries, whereas mental cultivation has no boundaries.

In Chinese martial arts, the concept of Yi (意) – Intent – is often expounded upon. Xing Yi Quan (形意拳) and Yi Quan (意拳) place such importance on Yi that they incorporate the term in the name of the style.

In the practice of Taiji Quan, Qigong, and other Internal styles, we find phrases such as “Yi Dao Qi Dao (意到气到) – Where the Intention Goes, the Vital Energy Arrives.” This is often simplified as “Intent Leads the Qi.”

Yang Chengfu emphasized “Yong Yi Bu Yong Li (用意不用力) – Use Intent, Not Brute Force.” And in Xing Yi Quan there is this maxim: “Xing Yi Xiang Sui (形意相随) –Xing/Physical Movements must be imbued with Yi/Intent, otherwise the movements will be an empty vessel.”

When we look deeper into character Yi (意), we find that its core structure is composed of the top character Yin (音) – which means sound, tone or voice, and the bottom character Xin (心), which can refer to heart, mind, center, or core.

When we look at Xin from the perspective of Western medical science, it simply means the heart, the powerful muscular organ that pumps blood. However, the concept of Xin in ancient Chinese tradition is viewed as the organ of thought, temperament, contemplation, feelings, and emotions.This is why the translation of Xin, especially as it is applied in Nei Jia – Internal Chinese Martial Arts – is referred to as Heart-Mind.

The idiom, “Xin Yuan Yi Ma (心猿意馬) – Heart like a Monkey, Intention like a Wild Horse,” generally refers to a restless mind. The opposite of the restless mind is described by the saying, “Xin Bu Dong (心不動) – The Heart-Mind Remains Unmoved.” Both concepts, Yi and Xin, are essential for cultivating the mind, which is the gateway to deeper knowledge and the higher aspects of the art that transcend mere physical skill.
