The text is taken from the teaching which Peter gave orally during a retreat in August 2002: the 7 days of the retreat gave takes the form of the 7 chapters, for a fruitful dialogue between practices and theoretical principles.
Knowing too much may give me the impression that I see the world, reality, but this is an illusion: I see what I know and not what is. To have too much know-how can give me the impression of being in the world, but this is an illusion: I project the past into the present. Taking support exclusively from my knowledge and expertise in my relationship with the world, puts me outside of life, that which is renewed each moment.
