"Since Sandplay is one of the few therapeutic techniques in which language skills are unnecessary for understanding the expressions of the psyche, it has truly become a cross-cultural method that is now practiced therapeutically worldwide. Within this ever-shrinking world, Sandplay now offers us a unique opportunity to view universal, archetypal patterns as well as observe the unfolding development of the individual psyche."
