DO have bright, beautiful lighting. A beautiful chandelier is a wonderful addition to the dining room. If yours isn't bright enough or attractive to you, replace it with another fixture. Lighting is very auspicious.
DO hang mirrors here. Mirrors are stimulating and they double the good times by doubling the food and company in the room.
DON'T have clocks in the dining room. Clocks in the dining room bring bad energy; actually, they symbolize death. Remember, the passage of time is not important while you are enjoying a meal and the company of those closest to you. Take clocks out of the dining room.
DON'T eat with the dead. So many people have pictures of deceased relatives in the dining room. Avoid doing this because it creates an extremely yin dining experience -- and that can create health problems.
DON'T eat with animals. It is better not to have animals in the dining room, real or otherwise. If you have pictures of birds or statues of animals -- or even your dog, Spot -- take them out of there. Animals symbolically eat your food. Better to put them in another location.
Arguments start at the table? Excess wood energy is to blame. Put a red tablecloth on the table to diffuse arguments and exhaust the wood energy that gets everyone bickering. The red color will make everyone hungry and focus on the food.
