"Working with material in general, and slime in particular, addresses this very human need to grasp onto something concrete in order to touch more abstract psychic materials. The possibility of grasping a finite object provides the client with a means to safely explore the infinite realms of his psychological existence. Particularly in the case of slime, its texture will gradually become more slippery and smooth, thereby allowing the client to eventually `liberate` themselves from the slime`s grip and become separate from it".
