Everyone has their own needs and style, mine is deliciously dramatic (because in my own private practice I have allowed myself to be as over the top as I feel like) but it starts with my sitting or lying somewhere comfortable and then doing a step by step visualisation. Firstly I envisage two iron bands encircling me, horizontally and vertically so that they create a spherical space around me. At this stage I always here an audible “ker…chunk” when the bands lock into place. Then the rest of the sphere bursts into life with licking tongues of blue fire which I hear hissing and spitting. Finally bolts of blue electricity arc around the iron bands crackling as they go. Inside I am snug and tucked away from the world.
