There is an assumption in our culture that unspoken and unwritten thoughts simply disappear. We have no evidence that they survive, but neither have we evidence that they vanish, violating the law of conservation of a still unknown mass or energy.
Three places make me favour the hypothesis that thoughts do not degrade as rapidly as we ... think.
The first place is a Breast Care Centre where I have a yearly appointment. It is a place in the basement of a hospital where many women who have experienced breast cancer wait to see a surgeon, or an oncologist, or to have a mammogram. Before I go I take the precaution of applying underarm antiperspirant but, long before I am seen by an expert, my clothes are damp from the sweat of fear. Yet, during the year following my diagnosis I managed to live five days a week for five weeks in a hostel on the site of the hospital where I was having radiotherapy. This hospital was situated in grounds where mature trees grew, birds made their home and laughter could often be heard. I remember my stay there as a happy one.
Self preservation is an even more basic animal instinct than defence of territory. Confronted by a predator we have the biological equipment to enable us to fight or flee; but it is impossible to vanquish quickly or escape from the predator called cancer. Fear is an emotion designed to galvanise us into action. We feel trapped when we have to spend lengthy periods in a waiting room, haunted by the trapped thoughts electric with emotion of those around us and those who have waited there in the past. There is, I sense, a terrifying jinn in the Breast Care Centre.
The other places are both kitchens with tiled walls and floors, where an unhappy thought seems to pull towards itself previous unhappy thoughts that have been lurking in the walls, waiting for an opportunity to invade what I think of as my mind and to have fun disturbing me until they become exhausted.
Last week I saw a table and chairs in a shop window, fell in love with them and bought them. We badly needed new chairs and our kitchen table had been inherited by my mother. When they were delivered I felt a calmness enter the room. Only then did I realise the significance of the wrought iron in the chair backs. Jinn are deterred by iron and now I can think a single unhappy thought and then let it go, without being plagued for hours by its associates.
