Interview about the fourth way

In this conference within the frame of the Journées Internationales de la Spiritualité Laïque, Philippe Muller initiates to G.I. Gurdjeff 's fourth way  which is both a way of knowledge of oneself and an inward work.
He lightens his approach almost scientific based on observation and understanding of energies which are in us and dysfunction of our mental, emotional and motor functions, which grow

and grow consciously. He shows the particularity of work on body and will, allowing learning being transformation.
What are the stakes of "knowledge" and "being"? How to grow with our questions? What efforts to make to transform us?
