Heart Fire in Chinese Medicine refers to emotions that may raise the thermostat in your “cool” Heart. All movements in this Treasure use the horse (riding) stance which allows us to truly connect with our legs so we can root those emotions for the Heart to be able to listen to them without running the risk of overheating!. Sit as low as you can in the horse stance but do not strain. Only do as much as is comfortable. You will build strength with consistent practice.
