The Bagua is made up of 8 Gua's (sections), each focusing on a different life area, with the center focusing on balance and health. The Wealth and Prosperity Gua is a favorite among most people -because everyone is interested in increasing or securing their personal wealth.
Wealth is not just about money though. Wealth and Prosperity can be represented by having food to eat, a healthy life, support in relationships, a home to live in, etc. Wealth and Prosperity is about a secure life, which is and continues to grow and prosper.
The Wealth and Prosperity Gua is identified with the element of Big Wood. Think maturing trees, flowering, full. Think about tall, healthy growth in trees.
The color purple is considered wealthy and luscious. Also think of greens, blues and reds. All the colors you might see at the end of the growing season.
Since water supports wood, a fountain would be a nice addition in this area.
Fire ignites, therefore, a red accent can spark this area.
Just remember to focus on healthy growth, lush greenery, and items that feel luxurious. Anything that says "wealth" to you.
Wealth and Prosperity is achievable for everyone. If you have food to eat, a home to live it, a good job, friends and family - you may find you are already "wealthy". Now, just prosper!
