Dr. Mori explores Buddhism through his perspective as a robot engineer. He even postulates that robots have the buddha-nature. He confronts Buddhist themes such as the notion of ego as if they were engineering problems and comes to surprisingly clear resolutions.
Along the way, he poses many interesting questions that perhaps only a robot engineer would think of. Why do we have two nostrils -- not just one? Why don't we have "earlids" similar to eyelids? His inquiries are highly engaging.
