In traditional Chinese cosmology, the "Twelve Stages of Life and Death" is an important theoretical system that describes the state of the heavenly stems in different earthly branches. This article will explore in depth the yin and yang attributes of the Twelve Stages, revealing the mystery of whether the "Stages of Life" belong to yin or yang, helping readers better understand and apply this ancient wisdom.

The Yin-Yang Cycle of the Twelve Stages of Life and Death
The "Twelve Stages of Life and Death," also known as the "Twelve Stages," is a term in traditional Chinese cosmology describing the life and death states of heavenly stems in different earthly branches. It follows the principle of "yang dies, yin lives; yin dies, yang lives," forming a taiji-like cycle. This cycle not only reflects the mutual transformation of yin and yang but also deeply embodies the natural law of continuous creation and renewal.
The Stages of Life for Yang and Yin Stems
In the Twelve Stages of Life and Death, the five yang heavenly stems (Jia, Bing, Wu, Geng, Ren) and the five yin heavenly stems (Yi, Ding, Ji, Xin, Gui) each have different sequences of stages of life. The death place of yang stems corresponds to the life place of yin stems, and vice versa. This rule reveals the mutual dependence and transformation between yin and yang.
The Stages of Life for Jia Wood and Yi Wood
Taking Jia Wood and Yi Wood as examples, Jia Wood's stage of life is in the Earthly Branch of Hai, symbolizing a seed state, waiting for growth; while Yi Wood's stage of life is in the Earthly Branch of Wu, representing the beginning of blooming and fruiting. Jia Wood dies in Wu, indicating that trees are at their weakest in the height of summer and begin to store nutrients again; Yi Wood dies in Hai, meaning that grass and trees wither in winter, and leaves fall off. This illustrates the principle that yang stems represent images, while yin stems represent forms.
The Stages of Life for Bing Fire and Ding Fire
Bing Fire's stage of life is in the Earthly Branch of Yin, symbolizing the rising of the sun, and the beginning of growth of trees in spring; Bing Fire dies in You, representing the setting of the sun and the loss of its fiery power. Ding Fire's stage of life is in You, representing human fire, such as lamps and cooking fires; Ding Fire dies in Yin, as the lamps lose their necessity after the sun rises.
The Stages of Life for Geng Metal and Xin Metal
Geng Metal's stage of life is in the Earthly Branch of Si, indicating that metal is born in fire and must be smelted to become useful; Geng Metal dies in Zi, where metal is buried in water. Xin Metal's stage of life is in Zi, representing underground water transporting metal elements to form ore deposits; Xin Metal dies in Si, having been smelted into a new shape.
The Stages of Life for Ren Water and Gui Water
Ren Water's stage of life is in Shen, representing a source of water or a spring; Ren Water dies in Mao, as it is weakened by the growth of wood. Gui Water's stage of life is in Mao, representing the arrival of rain and dew in early spring; Gui Water dies in Shen, as rain seeps underground to form a spring.
Through an in-depth analysis of the Twelve Stages of Life and Death, we can see that the yin and yang attributes within the Stages of Life are mutually transformative and interdependent. The sequences of stages of life for yang and yin stems not only reflect the continuous creation and renewal of nature but also provide us with essential tools for understanding and applying cosmology. Through this article, we hope to help readers gain a deeper understanding of the yin and yang attributes of the Twelve Stages, thus advancing further on the path of cosmology.
