"All that is visible must grow beyond itself into the realm of the invisible."
-The I Ching
"All poetry is inherently mystical. In the first and most basic way, its primary aim is to communicate at nonrational levels. Metaphors exist to convey, or evoke, or create sensibilities that cannot be conveyed or created using direct terms. For our purposes, this means metaphors evoke 'feelings' in the range of emotions, but also sensibilities, in the range of intuitions, and of moral and spiritual senses of meaning which are very difficult or impossible to express directly."
"Metaphors for Reality: The Sufi metaphor of intoxication as a spiritual state is partly figurative but partly literal. Intoxication is a metaphor for madness, and madness is a metaphor for the spirit's condition, or transformation, or unfolding into reality, in the presence of the Divine. But amazingly, where poetry and music are involved, intoxication is not only a poetic figure, but is also a literal condition of the body as well as the mind. Poetry's music and imagery affect the body and the mind - the exterior and interior - alike, as if they were the same thing."
