What is the 5th Line?

In Gyrotonic, there is a concept called the “5th Line”.  Rather than a physical place, the 5th line refersto reaching out in all directions from one’s major “power center” located in the lower abdomen.  It can be compared to central currents of electricity that move through the spine, the arms and the legs.  It’s almost like you are a starfish freely and fully; taking up the space within and around you no matter your shape.  The word yoga translates as “union” and 5th Line shares this sense of well being, calm, connection and vitality.
