Chi or Ki is the non-physical energy in all living things. Ki is flowing in everything that is alive including plants, animals and humans. When a person’s Ki is high, they will feel strong, confident, and ready to enjoy life and take on it’s challenges. When it is low, they will feel weak and are more likely to get sick. We receive Ki from the air we breath, from food, sunshine, and from sleep. It is also possible to increase our Ki by using breathing exercises and meditation. When a person dies, their Ki leaves the physical body.
