“We are all actors: being a citizen is not living in society, it is changing it.”
World Theater Day Message, Geneva, Switzerland (2009)
“Truth has no path. Truth is living and, therefore, changing.”
                                        
                                        This statement probably derives from a famous one of Jiddu Krishnamurti: "Truth is a pathless land." 
Tao of Jeet Kune Do (1975)

To know oneself is to study oneself in action with another person. Awareness has no frontier; it is giving of your whole being, without exclusion.
