“All the beautiful corners of the world are the greatest mind and body healers!”

“Having a body is in itself the greatest threat to the mind... The body encloses the mind in a fortress; before long the mind is besieged on all sides, and in the end the mind has to give itself up.”

“The greatest crimes in the world are not committed against the body, but against the freedom of the consciousness.”

“A contented mind is the greatest blessing a man can enjoy in this world.”

“It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.”

“Walking shares with making and working that crucial element of engagement of the body and the mind with the world, of knowing the world through the body and the body through the world.”
