I think I've now cleared this all up.
Last night after doing my first set of NAP rituals at around 11pm; I performed the banishing rites three times with command/authority/conviction that my will in banishing was something from which I would not yield. I was performing the banishing in a provocative confrontational manner.
Halfway through the second time I encountered 'resistance', and by the third time my eyelids were fluttering rapidly and I saw on the inside of my eyelids a black hulking humanoid. I was experiencing wild 'chill' sensations which I've come to associate with the power of 'spirits'. It was a little bit of a tug-of-war at this point, but it was basically concentration and will which saw me through.
Afterwards I felt clearer and with a stronger sense of wellbeing. I went to sleep soon after.
I woke at 3am full of energy and feeling warm. I expected the 4:30am presence to return so I went into meditation to prepare myself before drifting into sleep with earplugs.
I awoke at 4:20am once again to footsteps which sounded louder than usual almost because I refused to notice them. I knew from my past NAP journal entries that in a few minutes the room would feel cold and I've feel cold pressures glancing me. My idea of 'banishing' which proved successful was really the deep realisation of many concepts I'd previously thought I understood. In asserting myself I realised that self-esteem is a part of who you are which is fundamentally inviolable if you accept ownership of it. I learned that being assertive flowed from a fundamental right to exist -- in whatever minute sense -- as a bastion of liberty unto yourself; that in some way I was an essential being which could not be tarred without consent.
There were a few waves of 'chills' which ran through my body, and I answered each with the resolution that I would not waver in response -- that although an ocean is impossibly vast, waves will always break when they meet rock.
I also went over the NAP banishing in my mind with whatever limited understanding I actually had of the underlying theory. The sounds seemed to get worse (as if to break my concentration) though it's hard to say because I was focussed on being resistant
I now understand why we call it 'grounding' by the end it felt like I was a lightning rod which allowed everything to be discharged and neutralised to a point of equilibrium. That said, when this was all done the room felt SO much clearer. I SUDDENLY had a sense of well-being and freedom which indicated to me that no matter how doubtful I chose to be, SOMETHING had happened -- regardless of whether I wrestled with spirits or projections of my own mind. There was no 'visualisation' involved, everything was apprehended through physical senses.
Anyway this has all been pretty new for me. Hopefully I actually have practical magical skill to show for it at some point so it's not just a 'mystical experience'. Once I've gotten what I need from NAP I want to aim for physical manifestation with another system so everything is objectively real and visible without a shadow of doubt.
Where I am now it seems like banishing depends more not in what you say but how you say it?
IDK.
Thanks again all!
