The blister from a cold nail
Content note: health claim (mind can shrink tumours — his inference)
The story — as told by Ajahn Brahm (verbatim captions)
hypnotized him and they had a piece of wood with a nail on the end, very simple equipment, didn't need much to buy a nail and a piece of wood and they hypnotized this guy to believe that the nail was red-hot. It was just room temperature and they touched the nail on this man's skin, he screamed in pain because he thought it was hot, you can understand that, but to see a blister come up on his skin, that was weird

A reflection (in the spirit of Ajahn Brahm's talk)
At a Cambridge demonstration, a hypnotised student was told a room-temperature nail was red hot. He screamed, and a blister rose. Ajahn Brahm saw the mind's power. Hope helps healing. Hopelessness harms. It's not medical advice and no reason to skip treatment. But a hopeful mind helps you through.
In brief (our summary)
At a public demonstration of the Cambridge psychical research society, a student is hypnotised to believe a four-inch nail on a stick is red hot. It's at room temperature. When it touches his skin he screams — and, to Ajahn Brahm's astonishment, a blister appears. He reasons: if the mind can raise a blister with no physical cause, why can't it shrink a tumour?
Teaching point
The mind is powerful; confidence that it can heal matters.
