The mind controls so much of the body. We are much more than flesh and blood we are complex systems. Patients do better when they have faith that they're going to do better. That's why I always tell my patients and their families not to neglect their prayers. There's nobody I don't say that to.
Poetry is a special use of language that opens onto the real. The business of the poet is truth telling which is why in the Celtic tradition no one could be a teacher unless he or she was a poet.
