Validating [psychotic] experience and linking it with that of the mystic wherever relevant was an obvious first step. This was coupled with a realistic appraisal of the problems of trying to conduct life from the transliminal (which I often compare with trying to drive a car from the back seat, without proper access to the controls) and encouragement to join the ordinary world along with strategies for managing this.

As I said at the beginning of the last sequence of posts, I am aware that the full focus of my current enquiries spreads across this whole diagram. However, I needed to start somewhere manageable and progress from there, or else my next blog post will have to wait several years until I have had time to explore the whole diagram.
It should be surprise to regular readers of this blog that I decided to start with the left side. I’m not sure what the brain laterality implications of that are exactly, but I’m very clear that I’m trying to play to my strengths here. The most enriching part of my career was spent working with the experiencers of psychosis. That’s the work I loved most and where I learned most.
Even so this is not going to be plain sailing and this voyage is probably not for the faint-hearted blogger.
As I have hopefully shown in the first sequence of posts, it’s now easy to demonstrate that trauma plays some kind of causative role in psychosis, as well as in other distressing problems.
What I hope to illustrate is how transliminality, a permeable threshold of consciousness, or something like it, appears to correlate with some experiences of psychosis. My first problem there will be trying to clarify exactly what transliminality is.
After that, what may not be so easily supported by evidence is the idea that transliminality is also playing a causative role. It may simply be another consequence of trauma: in fact, there is some evidence to that effect. To close in on resolving this I will need to search for evidence that transliminality, at least with some people, is present prior to both trauma and psychotic experiences: I am still in the process of trying to pull that evidence together, but it is not proving easy. What I will be giving here is more of a progress report rather than a final position on the matter.
What is Transliminality?
I think we have to start by attempting to define what transliminality might be. Gordon Claridge in Psychosis and Spirituality pins his colours to Thalbourne’s mast (page 82):
As defined by Thalbourne, transliminality refers to a individual differences in the extent to which ideas, affects and other mental contents cross the threshold between subliminal and supraliminal: in some people, he argues, the barrier is simply more permeable. . . . . Quoting a range of psychometric, clinical and experimental evidence, he argues that a high degree of transliminality is associated with strong belief in and reporting of paranormal phenomena; enhanced creativity; a greater tendency to indulge in magical thinking; more frequent mystical experiences: and a susceptibility to psychotic and psychotic-like symptoms.
This though, I think, jumps too far ahead for present purposes.
For a start, it is necessary to flag up one fundamental complication that I will be seeking to address, though I may be unable to come to any definitive conclusion empirically on the basis of the evidence that is available to me at present.
I am sensing that two distinct possibilities are being conflated, perhaps through my distorting one of the sources I’m consulting (Psychosis and Spirituality), or perhaps because the overall picture conveyed by the text is confused on this point. I believe that there are two quite distinct processes which have been subsumed into the supposedly single concept of transliminality.
I’ll try and unpack my point as simply and clearly as I can.
One possibility is that of a filter within the brain to prevent consciousness being overwhelmed with brain data it does not need. This data is what I suspect Claridge means by ‘affects, ideas and other mental contents,’ but the inclusion of mystical experiences seems anomalous for reasons I will explore later.
The basic brain filter function has taken its present shape via evolutionary processes. As we will see this filtering process has both costs and benefits.
The other possibility is a spectrum issue. Just as our senses cannot detect sensory stimuli except within a relatively narrow range, so our brains within our Western culture mostly fail on a whole to detect any signals outside this physical spectrum.
I am hoping to determine, from the evidence I am able to look at, whether psychosis is the result for the most part of leakage in the filter system. This would not mean that psychotic experiences should be dismissed as garbage: they are the meaningful responses to trauma and life experience and, if addressed respectfully and attentively, can catalyse a healing process as well as build a ladder to higher levels of emotional and cognitive understanding.
There may also be extended spectrum effects in operation: the factors that have altered the brain’s filtering mechanisms may also have enhanced its receptive capacities in other respects sometimes. That’s not as simple as it sounds as we will see.
Creativity would usually, I suspect, come from either increased filter permeability or extended spectrum perception. Psi and other mystical states would seem to me to be dependent only on the latter, though I’m not sure that this is the position Thalbourne would espouse — again something for later exploration.
The simplest way I could express this in a diagram is the one above.
I know it begs a lot of questions at this point but basically it is showing consciousness as a narrow-angled access to only a small proportion of all that might possibly be known. I have broken with tradition in placing the segment symbolising what we can access, not at the centre, but at the side. This is both to emphasise my ignorance of how this spectrum works and to suggest that our consciousness is not necessarily focused on what is central and most important.
The darkness surrounding it assumes our finite minds could never grasp all that there is: assume the black is infinite. We can at times access aspects of our usually unconscious inner experiences. The diagram assumes, perhaps incorrectly, that external realities beyond the reach of our ordinary senses can sometimes leak into the internal subliminal where they can infrequently be accessed, though perhaps not in an accurate or easily intelligible form.
It also assumes that the only way access to aspects of the initially extrasensory can routinely occur is when our receptivity increases: I am not positing some kind of filter mechanism in this part of the process.
At present this is largely a speculation to be tested, but it will help you follow the trend of my examination of the evidence if you bear it in mind.
Where possible and appropriate, instead of, in my commentary on quotations, using the term transliminality all the time, I will see if making the tentative distinction between filter and spectrum language helps make things clearer, as well as drawing a distinction between extrasensory and subliminal.
This is where I found Myers’s language confusing in my first encounter with him in the book, Irreducible Mind. Subliminal for him was a catchall term for anything of which we are not conscious. None the less he also used the spectrum model, and I did not pick up, from the Kellys’ transmission of his ideas, whether he distinguished between outside elements that were beyond the reach of our radar and internal elements that were below the threshold of consciousness.
I think this distinction needs to be made and will be revisiting Irreducible Mind in case I have missed something there. What I suspect I will not be able to avoid considering at some point is the whole vexed question of the mind-brain relationship. This may or may not make it easier to resolve the possible tension between filter and spectrum theories.
For now though, I am just going to start in the next post from the brain basics and work my way up from there.
