1.1 Introduction
1.1.1 Two Models of Qi Flow in the
Channels – Historical Overview
There exist essentially two views about the direction of the Qi
flow in the channels, which are based on different understand-
ings of the Qi movement within the body (➞Pirog 1995,
Manaka 1995/2004). For a better understanding of either model,
imagine a person extending his/her arms towards the sky
(➞Figs. 1.1 and 1.2).
Centripetal circulation model
The centre of classical Chinese cosmology, which describes
humans as standing between heaven (Yang) and earth (Yin),
includes the mutual relationship, influence, and dependence
between cosmos and man. Accordingly, early records of the
pathways (➞see appendix) depict the (11/12) channels as path-
ways that originate at the extremities, flow towards the centre of
the body and terminate either on the head or the torso. This is
the distinguishing feature of the centripetal circulation model
(➞Fig. 1.1).
This model is also present in the theory of the five shu-Trans-
porting points (➞8.1.6). The macrocosmic Qi enters the body
at the tips of the extremities and can be compared to the course
of a river. It begins very dynamically as a well, spring and
stream, expands to form a river and flows into the wide, deep
sea at the elbows and the knees and then further to the internal
organs via the channels.
According to this model, the functions of the channels can be
compared to antennae, which receive the cosmic influence,
transmitting it into the body. The Qi flow in the channels is
always from distal (coming from the Exterior, entering at the
tips of the extremities) to proximal (towards the centre, flowing
towards the internal organs). Each channel connects man with a
different part of the cosmos, which can be identified by a
numerological structure. Thus a relationship was assumed
between the eight extraordinary vessels and the eight trigrams
of the Yijing(➞1.7). The primary channels reflect the 12
earthly branches and the 10 heavenly branches. Since the early
records only mention 11 channels (➞Appendix 2), they were
counted as 10 channels on the arms and 12 channels on the legs.
Later, the 12 primary channels were mainly associated with the
12 earthly branches – the 10 heavenly branches rather repre-
senting the Five Phases model (note: the earthly branches can be
included in the latter as well).
Self-contained circulation model
In the course of the development of modern Chinese society, the
idea of a close relationship between man and cosmos (as a
heaven-earth-man model) became weaker. The channel system
was now increasingly compared to phenomena created by man
himself such as canalsand drainage ditches. The importance
of the original connection with the cosmos declined while that
of relationships within society was on the rise. Chinese society
became more complex, forming a self-contained unit. Similarly,
the concept of the channels as a connection to the macrocosm
was partially abandoned and the Qi flow is described as inde-
pendent and self-contained (➞Fig. 1.2). According to this self-
contained circulation model, Qi can flow forward as well as
backward – from the outer extremities to the Interior of the body
and from the Interior to the Exterior.
