There is always a state of feeling, it is a condition of embodiment, largely, but if all bodily sense were to suddenly vanish, that very absence would be the state of feeling, just as, on a smaller scale, a neutral mood is still a mood. To refer to a state of feeling rather than just a feeling emphasises its semi-stable and non-volitional character; it moves slowly so as to be the background against which apparently volitional thinking takes place, but strictly it is still a kind of thought, what else could it be? having no being outside of experience. Whatever it is that you take yourself to be inhabits these pervasive states of feeling; you can't touch their core, you think always from out of them. So, in a way it is a mode of thought that thinks you as the thinker of discursive thoughts, as the free witness of flowing experience, and hence the struggle to read its hidden logic.
