I just spent an hour negotiating with an entity which was so sure of itself, so polarised and so fixed in its ways that I want to invent the term "king entity" to describe it. This entity rested on a very deep sense of unhappiness as if unhappiness is the only reality. At the same time, it issued a constant stream of bitterness and anger which apparently bathed this unhappiness and kept it real. If you spend time with this entity you end up acting as if everything is fundamentally and eternally unhappy (and the main goal in life is to defend yourself), as opposed to the more penetrable belief that "I am unhappy now because ..."
To disintegrate this entity, I used every trick I have been practising lately - going into a trance while standing up (so I could spontaneously sway and bend to stir up the energy), holding back my shoulders to open up my heart and throat further, and opening up the flow of information from my neck to the top of my crown. All these tricks seemed to help.
At one stage I found myself repeatedly bending over then straightening up, as if to pump energies from the lower chakras upwards. I felt light penetrating from above me right down into my belly, and waves of awareness passing up through my head. There was also a kind of battle between good and evil happening between the front and back of my chest while the entity on my back tried to oppose the ideas coming from my heart.
I may have to continue purging some residue in the days to come, but I am not surprised to have to put in so much effort for what felt like a very deep and archetypal entity.
