This book covers all the basic concepts of Human Design; it delves into the inner workings of the nine Centers, the Authorities and the Four Types. It is an accessible support resource for students of Human Design. The book is written by Lynda Bunnell, an experienced teacher and the Director of The International Human Design School (IHDS). She has been inspired by the benefits of the Human Design System in her own life. This book motivates people to enter "The Living Design Experiment," and supports their resolve to de-condition.
