Generally speaking, yin is characterized as feminine, still, dark, negative, and an inward energy. On the other hand, yang is characterized as masculine, energetic, hot, bright, positive, and an outward energy.
Yin and yang elements come in pairs, such as the moon and the sun, female and male, dark and bright, cold and hot, passive and active, and so on.
But it is important to note that yin and yang are not static or mutually exclusive terms. The nature of yin yang lies in the interchange and interplay of the two components. The alternation of day and night is such an example. While the world is composed of many different, sometimes opposing, forces, these forces still coexist and even complement each other. Sometimes, forces opposite in nature even rely on each other to exist. For example, there cannot be a shadow without light.
The balance of yin and yang is important. If yin is stronger, yang will be weaker, and vice versa. Yin and yang can interchange under certain conditions so they are usually not yin and yang alone. In other words, yin elements can contain certain parts of yang, and yang can have some components of yin.
It is believed that this balance of yin and yang exists in everything.
Crystal grid and healing sets are groups of stones that go together for a purpose. Sets of crystals and stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing. Some are generalized and others have specific purposes.
