"Single Whip strikes a majestic pose.
Unobstructed are the mai luo passageways.
The spirit perked, the form alert.
Arms like a snake span East to West.
Attack the head; the tail swings to defend.
Attack the tail; the heads springs to counter.
Attack the center; head and tail jump to act.
Top and bottom and the four sides are thus guarded.
With the readiness of a stretched bow.
Where is the source of this ingenious posture?
Follow the backbone joints to its core."
- Chen Village Taijiquan Song
