Metaphor

While not specifically part of the psychology, metaphor is a common aspect of Buddhist teaching. The Buddha frequently taught in metaphor; the well-known story of the blind men and the elephant is cited in early texts. Metaphor is a powerful way to explicate simultaneously at different levels, and therefore expand mental function.
My work uses metaphor extensively, including Schön's notion of generative metaphor. It provides yet another way of cultivating new thinking.
