“Once one recognizes the value of having difficult obstacles to overcome, it is a simple matter to see the true benefit that can be gained from competitive sports. In tennis who is it that provides a person with the obstacles he needs in order to experience his highest limits? His opponent, of course! Then is your opponent a friend or an enemy? He is a friend to the extent that he does his best to make things difficult for you. Only by playing the role of your enemy does he become your true friend. Only by competing with you does he in fact cooperate! No one wants to stand around on the court waiting for the big wave. In this use of competition it is the duty of your opponent to create the greatest possible difficulties for you, just as it is yours to try to create obstacles for him. Only by doing this do you give each other the opportunity to find out to what heights each can rise.”

“It is said that in breathing man recapitulates the rhythm of the universe. When the mind is fastened to the rhythm of breathing, it tends to become absorbed and calm. Whether on or off the court, I know of no better way to begin to deal with anxiety than to place the mind on one’s breathing process.”

“But who said that I am to be measured by how well I do things? In fact, who said that I should be measured at all? Who indeed? What is required to disengage oneself from this trap is a clear knowledge that the value of a human being cannot be measured by performance—or by any other arbitrary measurement.”

“In some ways suffering ceases to be suffering at the moment it finds a meaning, such as the meaning of a sacrifice.”
