未有天地以前，太空無窮之中，渾然一氣，乃為無極。無極而太極。太極者，天地之根荄，萬物之原始也。太極拳者，一舉動，周身俱要輕靈，尤要貫串。氣宜鼓蕩，神宜內斂。無使有缺陷處，無使有凸凹處，無使有斷續處。其根在腳，發於腿，主宰于腰，形於手指。由腳而腿而腰，總須完整一氣。向前退後，乃能得機得勢。若有不得機得勢處，身便散亂。其病必於腰腿間求之。上下前後左右皆然。凡此皆是在意，不在外面而在內也。有上即有下，有前即有後，有左即有右，如意要向上即寓下意。若將物掀起而加以銼之之意。斯其根自斷，乃攘之速之而無疑。虛實宜分清楚。一處自有一處虛實，處處總此一虛實。周身節節貫串，無令絲毫間斷耳。（原注云：此係武當山張三丰老師遺論，欲天下豪傑延年益壽，不徒作武藝之末也）。

Before Heaven & Earth existed, within the inexhaustible Emptiness was the Undivided One Qi, known as Wuji. Wuji gave rise to Taiji. Taiji is Heaven & Earth’s foundation & root, the origin of the Ten Thousand Things . In Taijiquan, as soon as there is movement, the whole body without exception must be light & agile, & it especially must be threaded through. The Qi should vibrate like a drum, & the Shen should be collected within. Do not allow there to be cracks or gaps anywhere, do not allow there to be bulges or depressions anywhere, do not allow interruptions anywhere. It’s root is in the foot, emitted by the leg, dictated by the waist, & expressed by the fingers. From the foot to the leg to the waist, it must be complete & a single Qi. Whether moving forward or retreating backward, you‘ll be able to seize the opportunity & become dominant. If there isn’t an opportunity to seize the advantage then the body will fall into disorder, the defect is certainly in the waist & legs, seek it there. Upper & Lower, Front & Rear, Left & Right, it’s all the same. This is, in all cases, about Intent, not an external concern but an internal one. If there is Above then there is Below, if there is Front then there is Rear, if there is Left then there is Right. If you need to rise upward then that implies a downward Intention. If your opponent desires to raise something, then you add Filing to his Intent. Do this & he’ll break his own root, you will undoubtedly repel him quickly. Empty & Solid must be distinguished clearly. Each place has a part that is Empty or Solid. Everywhere is always like this, both Empty & Solid. Every part of the whole body must be strung together, do not allow the slightest interruption.
