What is a “zengineer”? A word you won’t find in the dictionary! It’s a bridge builder between nondual awareness and reason. Meet Marcel Eschauzier, a Dutch native living in Belgium with his better half. He spent years traveling, doing corporate gigs and living across cultures. A nondual awakening in 2016 made him trade his suitcases for an inner journey and a desire to share the sublime simplicity he found. Five years later, his books were regularly topping Amazon’s philosophy charts. A practical engineer at heart, Marcel is also passionate about nonduality’s meaning for physics—hard to overstate but typically overlooked. Other interests include long walks and losing staring contests to the dog. Marcel holds a Master of Science in Industrial Engineering and Management Science from the Eindhoven University of Technology.
