Centers (Fourth Way) In G.I.
Gurdjieff's Fourth Way teaching, also known as The Work, centers or brains refer to separate apparatuses within a being that dictate its specific functions.

These centers in the human body are analogous to a three-storey factory, the intellectual center being the top storey, the emotional center being the middle one, and the moving center being the bottom storey.
