In nature:
Without day, there would be no night. Without winter, there would be no summer.
In the human being:
There are active people, because there are passive people. Everything exists only in
relation to each other.
Yin and Yang are opposites but are also mutually dependent on each other. Yin nourishes
Yang. Yang produces Yin. If Yang is weak, Yin is not produced sufficiently. If Yin
is weak, Yang can no longer be sufficiently nourished. Yin can't exist without Yang,
and Yang can't exist without Yin. Therefore, Yang Deficiency
can originate from Yin
Deficiency and Yin
Deficiency can originate from Yang Deficiency.
The Qi (Yang) of the Lungs supports the Heart in the Blood production. Vice versa
is the Qi of the Lungs nourished by the Blood (Yin) of the Heart. |
