ABSTRACT
This chapter exposes aspects that improve the discussion of Primordial Mental Activity, the first being brought about by an understanding of how epigenetic effects in specific brain regions, that is, heritable changes in phenotype that are not encoded in the DNA sequence of the genome, which mediate the influence of environmental factors on it, should be seen as promoting changes in pathophysiology. In addition, it is approached the concept of transliminality, that studies the developmentally and culturally dependent individual involuntary susceptibility to, and self-consciousness of, unconscious material that is affectively charged, depending on her changing environmental sensitivity to sensory stimuli. Finally, I point out two factors in the research of PMA in relation to Arts and mystical experiences that require further attention, that is, (A) the exploration of how the use of physical and/or primary metaphors should be analysed as gateways to understand affective engagement as developmentally construed in the individual and acted out and/or syncretically cognised through specific archetypal themes, leading to a categorisation of metaphors into byproducts that speak of specific mind/body experiences of relatedness, and (B) the problematisation of how Ayahuasca drinking neutralises inner working models that constitute the individual’s negotiation of intersubjective relationships.
