The Fourth Way resurfaced in the West at the turn of the twentieth century through the impulse of Gurdjieff. It does not require us to renounce the external world, but on the contrary is practiced while we continue to live our family, social, and professional life. It requires simultaneous work on the physical, emotional, and intellectual centers. The Fourth Way is called the "way of the clever man" since it enables one to produce a certain energy, a certain substance that permits an accelerated spiritual evolution.
