Zen and the Art of Motorcycle Maintenance
But now we have with us some concepts that greatly alter the whole understanding of things. Quality is the Buddha. Quality is scientific reality. Quality is the goal of Art. It remains to work these concepts into a practical, down-to-earth context, and for this there is nothing more practical or down-to-earth than what I have been talking about all along… the repair of an old motorcycle.
