"Play, from early childhood on, is a rigorous discipline--requiring acute focus and concentration (not all children do it well) along with unfettered ingenuity. It requires a wholeness of being and respinse that embraces our rationality and emotions, our logic and intuition."
"true play--therapeutic play--involves delight and surprise and risk [...]; it is an engagement of self with the otherness of the world where a mutual transformation of meta-physickal consequence may occur"
the idea about "self" and "the world" is derived from Winnicott's Playing and Reality: "The thing about playing is always the precariousness of the interplay of personal psychic reality and the experience of control of actual objects"
