Moving through the form one maintains peng throughout the body. This is seen in the rounded form of arms, shoulders, hips, back, legs, arm to hand. When the peng is not open and relaxed the body can become too tight. When the body is tight one cannot connect, connection is lost. Too loose and there is no power, no energy. Peng is like holding a baby. One cradles a baby gently. Too loose and the baby is dropped. Too tight and the baby is not comfortable and will feel the tension.
