According to Classical Feng Shui, stars shift if the sky. The stars in the Big Dipper relate to the energy maps we follow in Xuan Kong Flying Star Feng Shui. Each of the stars influence the environment. These stars change each year, each month, each day, each hour, and so on.
Ancient Chinese astrologers referred to the Big Dipper(Great Bear, Ursa Major) as a giant clock in the sky. Basing much upon the shifting position of stars and planetary influence, the change in the seasons, Yin and Yang, as well as the Five Elements of Feng Shui, we are able to understand the type of energy influencing our environment almost at any time.
The Five Element Theory (wǔxíng) in Feng Shui pertains to the characteristics related to shifting stars and planet influence on our environment and how these energies interrelate with each other in our environment. In Classical Feng Shui, 1-9 stars relate to one of the five elements. The five elements are (1) Water, (2) Wood, (3) Fire, (4) Earth, and (5) Metal. For example, the Misfortune #5 Yellow influences the environment through characteristic of the Earth element as does the Black Illness #2 star.
The production and weakening cycle refers to types of relationships between the five elements. As a continuing process such as the changing seasons, we usually get more rain in the Spring than we do in the Summer; a natural process changing in a natural pattern. The warmer the Sun (closer it gets to us), the more water becomes free and moving. Thus, the Spring showers bring May flowers.
In the production cycle of the five elements, we can think of Spring showers bringing May flowers as water producing wood. Further, wood produces fire and so on. If we see that a combination of stars is beneficial to us, we may decide to use the production cycle to further enhance the auspicious visiting star. So, if we want the wealth Earth Star 8 to be a bit stronger in a certain area of our space, we would only need to add a little fire element.
The weakening cycle is the theory of how the elements produced infuence the element that produces it. So, wood produces fire, but a lot of fire weakens (drains, depletes) wood. A lot of water, weakens metal. We use the weakening cycle against negative star influence. In 2020, the #7 metal star influences robbery, sharp objects. So, we introduce the water element to weaken the influence of the metal energy of the #7 star.
There is also a destruction cycle, but we very seldom use this cycle since it is so strong. There are situations where using the destruction cycle is feasible, but using the weakening cycle usually produces the results we want to achieve. Regardless of the cycle we use to minimize or maximize the potential energy of a star, we can never totally erase the continuous influence of stars in the heavens.
