Painting in calm and silence.
I've been reading about the value of silence in our lives. I noticed how noisy are our lives the first night at home after my treatment for pancreatic cancer in hospital.
The ward was a constantly noisy place, even at night. My bedroom was so quiet on the first night, I couldn't sleep. 
In 'The Spirit of Silence', John Lane writes of Paul Cezanne, his work
Arises out of a ground of calm and silence.
Cezanne is described by John Lane as not beginning with a belief in a transcendent reality but with fidelity to observed facts.
Unsatisfied with the Impressionist dictum that painting is primarily a reflection of visual perception, Cézanne sought to make of his artistic practice a new kind of analytical discipline. In his hands, the canvas itself takes on the role of a screen where an artist's visual sensations are registered as he gazes intensely, and often repeatedly, at a given subject.
Time and silence are the bedrock of this kind of reflection on what we see before us all.
