The strike by resident doctors highlights the severe tensions faced by the National Health Service. The tragedy of the dispute, and any disruption experienced by patients, is that all sides involved no doubt very much want health services to improve. So as resolution is sought can this also be a moment to ask again an increasingly pressing question. What exactly is health?

The issue often came to the fore when I worked in the NHS. My role was as a psychotherapist in a psychiatric hospital. We worked with older adults who had often suffered for not just years but decades. Their pain was substantial and entrenched. What could be offered to such folk? What did we mental health professionals think we were doing?

There were no easy answers. Suffering is hard. But a light might flicker in the darkness when a patient felt heard. They realised, even momentarily, that they were with someone who didn’t have any immediate remedy but did appreciate the depth of their torment.

Many doctors will know such moments. There is a glimpse of connection that is potentially healing and powerful. But why?

The answer provides a clue to a notion of health that is not only about an absence of symptoms, valuable though that most certainly is. With a patient who feels heard, you together enter a field of existence that is wider than the previously isolated, suffering soul knew was possible. A dimension of life, not determined by having solutions, is discovered as a release or expansion.

The word “health” itself recognises the possibility as it comes from the old English for “whole”. Believers in God will recognise that wholeness as an intuition: our existence as individuals is actually a sharing in the existence of God. We are as many reflections of the one divine light.

A shift of perspective, a kind of conversion, is required for this transcendent awareness to become a steady part of life. The difference with this fuller notion of health or wholeness is that you don’t privately possess it, let alone control it, but rather it holds you and you might collaborate with it more fully.

The NHS will likely continue to struggle with the demands it faces, even as - and perhaps because - remarkable improvements in treatments will continue, too. In this context, a cultural and spiritual conversation about the wider nature of health is crucial. Like the patient who feels better because they are heard, a more expansive vision of what health entails, and indeed what it is to live well, will alleviate stresses on us all.
