The kinesthetic five lines, the primary image, or the "primitives," as they're often called, are an imprimatura of the self as lines. it is just the leg lines, the spine line, the arm lines, and a lollipop head on top. Not muscles, bones, sinew, flesh or ligaments. Just lines. It's abstract, a schema. The lines have shape, distance, position, and movement, but it's not the "body" as your physical self. 

The lines are a representation of yourself to yourself. If you can work with the lines, it is a truly magical way of sensing.

Five lines: Finding wholeness

Here is my teacher, Dennis Leri, on this subject (edited for clarity):

“The primary image, or the five lines, is a way to embed a sense of yourself that is not transitory, ephemeral, or fleeting. You develop a touchstone that you can constantly refer to. When you have an address, you can calibrate really differently.

Once a pattern has been learned, it can be transferred to other places where it can be adopted. It's not just movement, it's locating yourself in space. The five lines are an image that helps you orient. It's not what you see, it's what enables you to see. It's in the background. It’s something in your own nature as a pattern of action upon which all other actions are predicated.”
