There is No Jin \u52b2 (Part 1) <\/span><\/h2>\n

by \u00a9<\/strong> Chun Man Sit<\/strong><\/span><\/p>\n

The ether<\/strong><\/p>\n

<\/strong><\/p>\n

In the nineteenth century, most scientists and physicists believed the entire universe was covered with a fixed, invisible substance called the ether, or the \u201cluminiferous ether\u201d, indicating that it was the bearer of light waves.<\/span><\/p>\n

After the speed of light was discovered to be 300,000 kilometers per second, many scientists tried to solve the mystery of the ether.<\/span><\/p>\n

The logic was quite solid: if there was ether, the movement of the earth must create a kind of \u201cether wind\u201d. They would use the speed of light and the movement of the Earth to prove the \u201cether wind\u201d. Many physicists tried and they all failed. The most famous experiment to find the ether wind was done by two scientists: Michelson and Morley. Michelson, who discovered the speed of light, was confident that they would find this wind of ether.<\/span><\/p>\n

After many years of hard work, they failed to find any proof of the ether wind. Michelson thought their experiment a failure. He found out much later that their experiment was a successful and revolutionary experiment in history: there is no ether wind!<\/span><\/p>\n

At the same time, while working as a clerk in the Swiss patent office, Albert Einstein used whatever free time he had to think about the universe and time. Then he wrote a paper called the special theory of relativity, which changed the way we looked at the world forever. He was young and quite bold.<\/span><\/p>\n

\u201cThe reason Michelson and Morley could not detect an ether wind,\u201d said Einstein, \u201cis because there is no ether wind.\u201d It is that simple!<\/span><\/p>\n

The Taiji Jin<\/strong><\/p>\n

\"\"<\/a>All serious Taiji students have heard of the mysterious jin, or nei jin. It is the holy grail of taijiquan. All taiji masters have this jin, or so they claim.<\/span><\/p>\n

According to the commonly accepted Taiji theory, there are two kinds of forces. The first force is called li, which is what we have before we learn taiji. The second force is called jin, which must be learned and acquired, preferably from a famous taiji master.\u00a0 Like a caterpillar metamorphoses into a butterfly, we learn Taiji and somehow change our force from li into jin.<\/span><\/p>\n

Here are some traditional sayings about the differences between li and jin:<\/span><\/p>\n

    \n
  1. Li is square and jin is round.<\/span><\/li>\n
  2. Li is slow and jin is quick.<\/span><\/li>\n
  3. Li floats and jin sinks.<\/span><\/li>\n
  4. Li comes from the bones and jin comes from the tendons.<\/span><\/li>\n<\/ol>\n

    There are many more similar ideas. They all seem wonderful at first glance. But after forty years of practice and research, I find some of those ideas are simply ridiculous. Li is square. What does it means? How does anyone try to prove this in a scientific way? Or should we assume that taijiquan is above the laws of physics?<\/span><\/p>\n

    \"\"<\/a>A tale of 35 jins<\/strong><\/p>\n

    In a famous Taiji book \u201cTaijiquan and Self-defense\u201d by Chen Gong, the author listed 35 kinds of jins. Then he tried to explain 25 of those jins. According to Chen, all these jins were difficult to achieve; and each one was harder to acquire than the previous one.<\/span><\/p>\n

    What about \u201cThe Dao is simple\u201d, and \u201cTaiji is just one yin and one yang.\u201d?<\/span><\/p>\n

    In a fighting situation, we must make split-second decisions, how can we choose one jin out of thirty-five quickly?\u00a0 For me, I\u2019m lucky if I can remember the names of the 35 jins., not to mention choosing the right one within half a second.<\/span><\/p>\n

    Master Wang, the founder of Yi Chuan, said, \u201cIn a fight, if you have to think and then respond, you are too late.\u201d If your timing is wrong, nothing will work.<\/span><\/p>\n

    What is li and jin?<\/strong><\/p>\n

    Li and jin are one and the same. They have the same substance, like water and ice. Water is melted ice and ice is frozen water. The secret lies in the temperature.<\/span><\/p>\n

    As for li and jin, li is frozen jin, and jin is moving li. The secret lies in the velocity of the motion.<\/span><\/p>\n

    When you use strength to cause tension, it\u2019s li; when you use strength to cause motion, it\u2019s jin. For example, when you hold on to a ball, you are using li. When you throw the ball, you are using jin.<\/span><\/p>\n

    To put it simply: li is tension and jin is motion.<\/span><\/p>\n

    Fa-jin, or issuing energy<\/strong><\/p>\n

    Fa-jin is a ballistic motion. The principle is simple: mass times velocity. The faster your fist hits the opponent, the greater the impact.<\/span><\/p>\n

    Speed is more important than mass because when you double the speed, you\u2019ll have four times the impact force. Triple it and you\u2019ll have nine times.<\/span><\/p>\n

    When you double the mass, you only have twice the impact. Plus a bigger mass needs more force to move. In other words, a heavy object moves slower than a light object.<\/span><\/p>\n

    A bullet can kill because of its tremendous speed. It can be so fast because it is small. The same bullet becomes harmless if it travels at 10 miles per hour. The ancient masters knew about this. The Taiji classic says, \u201cFajin is like shooting an arrow.\u201d\u00a0 This clearly means that fa-jin is a ballistic motion.<\/span><\/p>\n

    So the main thing we have to focus on fajin is speed. The rest is just icing on the cake.<\/span><\/p>\n

    If you are still not convinced, let me cite two modern Taiji masters\u2019 sayings:<\/span><\/p>\n

      \n
    1. Master William C.C. Chen talked about speed in his book \u201cBody Mechanics of Tai Chi Chuan\u201d. He gave an example of two different types of bullets to show the faster bullet had more impact power. And he also used the physic equation:<\/span><\/li>\n<\/ol>\n

      If you double the speed, you\u2019ll have four times the impact power.<\/span><\/p>\n

        \n
      1. Master Cheng Tin Hung of Hong Kong said, \u201cThere is nothing mysterious about jin. Jin is simply the skillful way of using li. They are the same thing. When someone\u2019s skill is very high, people think he has magical power.\u201d<\/span><\/li>\n<\/ol>\n

        Both Master Chen and Master Cheng are famous for their real fighting ability. Maybe we should listen to their advice. It has helped me to improve my skill greatly.<\/span><\/p>\n

        There is no jin; only mass times speed.<\/span><\/p>\n

        The jin theory was created in the old days to help us understand the motion of taiji. It was a good theory then. Nowadays we have better theories. We have Isaac Newton\u2019s law of gravity and his three laws of motion.<\/span><\/p>\n

        Use yi\/intention, don\u2019t use li\/force<\/span><\/p>\n

        The Taiji classic saying, \u201cUse yi\/intention, don\u2019t use li\/force\u201d is a correct way to move, according to Newton\u2019s first law of motion.<\/span><\/p>\n

        First Law:\u00a0\u00a0 Bodies move in a straight line with a uniform speed; or remain stationary, unless a force acts to change their speed or direction.<\/span><\/p>\n

        The key point is this:<\/span><\/p>\n

        Force does not cause motion; force causes changes in motion.<\/span><\/p>\n

        If you really understand this, you will understand that a good fajin uses very little force. Instead, it uses inertia. For example, after you shoot the arrow, it goes by itself because of inertia. You don\u2019t have to do a thing. In fact, if you do something to the arrow, you will change its motion.<\/span><\/p>\n

        Here\u2019s fajin is a nutshell:<\/span><\/p>\n

          \n
        1. Make a tight fist.<\/span><\/li>\n
        2. Relax the shoulder and elbow.<\/span><\/li>\n
        3. Use the waist or feet to shoot out the fist and forearm.<\/span><\/li>\n
        4. Hit the target as fast as you can.<\/span><\/li>\n<\/ol>\n

          There is no mystery in learning fajin. Fajin is not difficult; to do it faster than your opponent is difficult.<\/span><\/p>\n

          And you may not believe this: if you can punch faster than a taiji master, you can defeat him.<\/span><\/p>\n

          In fighting, the one with speed and power is the king; and speed is power!<\/span><\/p>\n
