The three feng shui gods of wealth, also called the three immortals, are a popular traditional feng shui cure that represents long life, fame, and fortune. There is a wide variety of legends about the gods of wealth.
One of the most popular legends is based on the belief that the three wise men, also sometimes called the three Star Gods, are the representation of specific celestials energies that are available for the benefit of humans. Let's look at the energies of each wise man - Fuk, Luk, and Sau - individually.
The Chinese character Fuk means blessings of good luck, health, and happiness. This is the wise man that is often depicted holding either a scroll or a child. There is a popular belief that Fuk is the personification of planet Jupiter, with all its associated energy of good luck and auspiciousness. The child is there to symbolize the transmission of this good luck to future generations, and the scroll can be perceived as the importance of knowledge/learning.
The meaning of Luk character in imperial China was an official's salary. It goes without saying that the energy of it is stability, fame, and success, as well as financial abundance. Luk is often depicted holding either a ru yi (symbol of power and authority) or a golden ingot, a popular wealth symbol.
Sau means longevity. This is the wise old man that is usually depicted with a very high forehead and a warm smile on his face. He is holding a staff, as he is old (thus the symbol of longevity). He is also holding a peach (considered a symbol of immortality).
The three wise men, or Fuk Luk Sau, are usually placed in an area with high visibility and good energy, such as a high table in the living room or on a high shelf in the office. It is thought to be disrespectful and bad feng shui to place Fuk Luk Sau on low surfaces, or in areas such as the kitchen, bathroom, or bedroom.
Fuk Luk Sau are always placed in a row in a specific order. To the left is always Fuk, with all the blessings and good luck energy. Luk is always in the center, with the promise of success and financial stability. Sau is to the right, smiling and offering the gifts of longevity and peaceful life.
Even though often called gods, the Fuk Luk Sau are not prayed to specifically, but they are always treated with great respect. You can see Fuk Luk Sau in most Chinese gift shops (look for the altar which is often in the back of the store), as well as restaurants, offices, and homes. Daily incense burning, candles, and fresh or artificial flowers are usually offered to these three wise men in hope of them bestowing their gifts on humans.
