Not long ago I had a first-hand experience of illness as metaphor. Suddenly I found that my sense of balance was completely out of whack. Moving my head made the world spin. As an audiologist I was quite aware of the irony of vertigo making me miss a meeting all about new discoveries in hearing science. But as a writer and a spiritual seeker, I was also aware of the metaphor. The frenetic pace of my recent weeks had thrown my whole system off balance. The metaphor was perfect.
