ENERGY SHIFTING CACTI

According to Feng Shui beliefs, plants with sharp and pointy leaves and thorns are destructive for Qi flow.  At the same time, the thorny cactus is an ancient Chinese symbol of preserving and wise spending. It is a cure for shifting energy and a catalyst for attracting wealth luck.
Good Feng Shui placement help gradually shift energy, bringing positive energy and wealth into the home.
