When we talk about Feng Shui, we are talking about the understanding and enhancement of energy. This means that Qi is the invisible forces or life force energy that is surrounding us. To find out if your Qi flow is high and vibrant, you can assess your energy level. How do you feel on a scale of 1 (tired all the time) to 10 (being full of vibrant energy)? Life force energy exists in us. If not, you will drop dead.
