Tai Chi and Hsing-i Differrences

•In Tai Chi the head is held as if slightly suspended from above, whereas in Hsing-i, the crown of the head gently presses upward, the bai hui point at the crown part of the head, has the feeling of being sucked inward;

•In Hsing-i, the teeth are slightly clenched but Tai Chi has them only touching;

•Hsing-i has a unique scissor step for directing earth root and whole body power;

•the so-called emotional mind, Xing, is not to be suppressed in Xing-i but guided by the thinking mind: this emotional mind
Animals use this emotional based mind because it is quicker;
senses to the thalamus, then to the amygdale in 12 milliseconds, most 'civilized' people use the cortex which takes twice the time at 24 milliseconds.

•Most Tai Chi practitiioners issue Qi for martial force, Hsing-i will use Qi also, but focus on Fa Jing (quick explosive internal power).

A good example of Fa Jing was when Kou Yu Chang slapped the back of a horse, and exploded the horses internal organs without any damage to the surface skin.

A major difference of Hsing-i, is that the first mind, the so-called emotional mind, Xing, is not to be suppressed, rather it is cultivated since Xing Yi imitates the animal form, mind and spirit. Most men in a fight; cannot match a wild animal half their weight.

In some other internal martial arts, and Qi Gong; the emotional mind is suppressed and dominated by Yi, the wisdom mind. This emotional mind is the fastest, as it is travels from the thalamus, then to the amygdale.

The renown researcher of the neurology of fear, Dr. Joseph DeLoux of New York University, in his book The Emotional Brain, found that there are two kinds of fear in the brain: fast fear and slow fear.

Fast fear travels the low road of the brain: senses to thalamus, then to the amygdale, which is located deep within the brain on the temporal sides; time 12 milliseconds. Traditional philosophy represents this separation as horse mind (slow) controlling the monkey mind (fast).

Slow fear travels the high road of the brain: senses to thalamus which sends it to the cortex (higher up); time 24 milliseconds. Both systems occur simultaneously, with the same sense data, the theory being that you cannot have speed and accuracy on the same circuit. Bear in mind, this is not the time to process the information, or physically move to react.

12 milliseconds or 1 hundredth of a second might not seem like much difference, but consider that there are some people that can beat a flash. Beating a flash is blinking your eyes when a photo is shot with a flash. The difference in speed between the flash, and camera shutter is one fiftieth of a second, or 2 hundredths. I and others can beat it trying, and by surprise, some just by surprise. Memory and choice have to go to the cortex, so they are slower; test your reaction theory with the flash.

With the foot steps, the true idea is to not fall into emptiness. Disperse the breath. The issuing is totally in the rear foot. Store up the intent. You need to protect the groin. If the beginning posture is good, then use ‘Sweeping the Ground Wind’.

Rooted steps are the scissor handles of the scissor-stepping that are driving the martial motion through one’s Lower Dan Tien (scissor’s axis pivoting point), that focuses the strike forward (scissor’s cutting tip).

In every movement, watch your Yi. When Yi generates the idea for movement, the Qi will be immediately led to the end section, starting the movement of the end section. The middle section follows and the root section urges the movement. This is not the same as Tai Chi, because the body in Hsing-i is more like rattan than water. Even though it is flexible, the body is hard so when the Yi is generated on the target, the tip can move first, and the power is pushed from the body and the root section.

Stomp while advancing; as a one would off a trampoline to launch a strike. This has a pedaling action forward, wtih the front foot directing and shaping the force issued by the rear foot.

The eyes must be venomous: acute, sharp and stern, with a mean and serious look. Your original Qi must be full and abundant in order to have these. Therefore, when practicing fist methods, it is training Qi and Li. Training Li is able to strengthen the body, and training Qi is able to enhance the spirit of vitality. Those whose Kung fu is deep, are able to gather the Qi at the Lower Dan Tien and the five internal organs are comfortable and expanded.

The highest level of achievement: the mind is mindless; you do nothing and have done everything. In the emptiness we find prenatal bodies. If you try too hard, it will elude you. Instead of trying to achieve it, pretend you already have it. The mind embodies your actions: therefore, Hsing-i is mind boxing.

This can not be reached through force or simply imitating.
See Entrainment

When it is time to be calm, it is quite and transparent. In this position, you are steady like a mountain.

In the beginning of the movement, the body remains soft so Qi can be led to the limbs. Hsing-i Jin is similar to rattan, soft and bending, yet hard when it strikes. The power is manifested like a cannonball exploding.

Learning Hsing-i:

•in the beginning it will appear simple and easy,

•when first trying the move it will appear complicated and difficult,

•after mastering Hsing-i, it will become direct and simple easily executed.

Martial Qi flows like mercury.
