In a 2003 horoscope,Rob Brezsny writes:
'Gemini performer Keith Hennessy teaches classes in improvisation. I'll quote his ideas about the subject because they perfectly describe the nature of the spirit you should invoke in the coming weeks. Here's his definition of improvisation. "The art of being in full awareness and integrity right now. The opposite of repression. The closest we get to the source language of creativity, soul, play, and magic. A crazy attempt to align body and mind not only in the pursuit of freedom, but in the actual experience of freedom. Intentional spontaneity. The beauty and truth of the wild."'

The way branches take shape, seeking sunlight, and responding to the wind, and how roots seek water and nutrients, and react to stones and concrete, may be a slow-motion improvisation of nature. If branches and roots did not seek freedom, did not explore, they would not grow.
