Recomendación de Lectura - Chen Xin

"During Taijiquan practice there is usually no need to orient one's initial position strictly to the cardinal directions. However, since the Big Dipper is placed north, the practitioner should respectfully face in this direction, since it is the source of inherent energy in the human body, known as Zhong-qi or Centralized Intrinsic Energy. Hence all diagrams presented in this book faces north, with the back to the south, the east at the right and west at the left.
To determine the way of heaven you need to resort to the
yin and yang substances; to establish the way of earth you need to apply the concept of soft and hard; to find the way of humans you need benevolence and righteousness"
