Wherever the mind goes the chi will follow and wherever the chi goes there will naturally be energy.
After many days and months the internal energy will become extremely sensitive and marvels will naturally manifest.
During practice the head must not incline to the side nor tilt up or down. This is what is meant by holding the head as if suspended from above, or the idea of balancing an object on the top of the head. In order to avoid a stiff vertical posture, we emphasize the concept of suspension from above. Although the vision is straight ahead, it sometimes follows the movements of the body.
The body should maintain an erect posture without leaning; spine and tailbone should hang in vertical alignment without inclining.
All the joints of the arms should be completely relaxed with shoulders sunk and elbows folded down. The palms should be slightly extended and the fingertips slightly bent. Use the mind to move the arms and allow chi to reach the fingers. After many days and months the internal energy will become extremely sensitive and marvels will naturally manifest.
One must distinguish full and empty in the two legs. In rising and sinking one should move like a cat. If the weight of the body is shifted to the left leg, then the left leg is full and the right leg is empty. If the weight is shifted to the right leg, then the right leg is full and the left empty. What we mean by “empty” is not a vacuum, for there is no break in the potential for power, and the idea of extension and contraction remains. What we mean by “full” is simply that it is substantial and not the excessive force is used, for this would be considered brute strength. Therefore, when bending the legs, the foreleg should not extend beyond the vertical. To exceed this is considered an excess of energy. If when pushing forward we lose our vertical posture, our opponent will take advantage of this to attack us.
When kicking with the front of the foot, we must pay attention to the toes; when kicking with the heel pay attention to the sole of the foot. Wherever the mind goes the chi will follow and wherever the chi goes there will naturally be energy. However, the joints of the leg should be completely relaxed and the kick should issue with evenness and stability. At this moment it is very easy to be guilty of using stiff force, wherein the body will rock and lack stability and the kick will have no power.
