"Love is the only force capable of transforming an enemy into friend."
"Life's most persistent and urgent question is, 'What are you doing for others?'"
"There can be no deep disappointment where there is not deep love."
"We must accept finite disappointment, but never lose infinite hope."
"I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality... I believe that unarmed truth and unconditional love will have the final word."
