In the field theories in physics, any particular region of the presumed space-time continuum and all interactions between elementary objects therein can be objectively measured and/or accounted for mathematically. Since this does not apply to any of thefield theories, or any other neural theory, of consciousness, their explanatory power is limited. As discussed in detail herein, the matter is complicated further by the facts than any scientifically operational definition of consciousness is inevitably partial, and that the phenomenon has no spatial (...) dimensionality. Under the light of insights from research on meditation and expanded consciousness, chronic pain syndrome, healthy aging, and eudaimonic well being, we may conceive consciousness as a source of potential energy that has no clearly defined spatial dimensionality, but can produce significant changes in others and in the world, observable in terms of changes in time. It is argued that consciousness may have evolved to enable the human species to generate such changes in order to cope with unprecedented and/or unpredictable adversity. Such coping could, ultimately, include the conscious planning of our own extinction when survival on the planet is no longer an acceptable option. (shrink)

A philosopher and a cognitive neuroscientist conversed with Buddhist lama Tilmann Lhündrup Borghardt (TLB) about the unresolved phenomenological concerns and logical questions surrounding “pure” consciousness or minimal phenomenal experience (MPE), a quasi-contentless, non-dual state whose phenomenology of “emptiness” is often described in terms of the phenomenal quality of luminosity that experienced meditators have reported occurs in deep meditative states. Here, we present the excerpts of the conversation that relate to the question of how it is possible to first have and (...) later retrieve such non-dual states of selflessness and timelessness that are unrelated to sensory input. According to TLB, a “pure” experience of consciousness contains the phenomenal quality of luminous clarity, which is experienced solely in the transitional phase from the non-dual state of absolute emptiness to the state of minimal emptiness, when the person gradually returns to duality. However, this quality of luminous clarity can also be experienced in non-minimal states as in the experiential mode of being awakened. TLB describes this transition as a kind of ephemeral afterglow in the form of a maximally abstract phenomenal quality, i.e., luminosity, which justifies the conclusion of having been in a state of “pure” consciousness.

The Sphere Model of Consciousness (SMC) delineates a sphere-shaped matrix that aims to describe the phenomenology of experience using geometric coordinates. According to SMC, an experience of overcoming of the habitual self and the conditioning of memories could be placed at the center of the matrix, which can be then called the Place of Pre-Existence (PPE). The PPE is causally associated with self-determination. In this context, we suggest that silence could be considered as an intentional state enabling self-perception to be (...) focused on the “here and now,” which in turn improves perception of one’s own body in space. To investigate these hypotheses grounded in the model, the current preliminary study examined the Place of Pre-Existence Technique (PPEt), in which practitioners are guided to focus on a self-defined aim; reach a state of detachment from the habitual self; envision the future. 481 volunteers PPEt practitioners completed self-report questionnaires before and after an intensive 3-day meditative training. We analyzed the possibly relationship between subjective experiences related to physical, emotional, mental, temporal, and spatial aspects, as well as self-determination and silence, before and after training. The results indicated a shift from a prevailing influence of mental dimension on the other aspects of experience, to a prevailing influence of spatial dimension. Silence was reported more often following the training, and predominantly related to the mental and emotional experiences. The results are discussed in relation to the shift from Narrative to Minimal Self and to increased balance among the considered dimensions. (shrink)

Many traditions have utilized silent environments to induce altered states of consciousness and spiritual experiences. Neurocognitive explorations of spiritual experience can aid in understanding the underlying mechanism, but these are surprisingly rare. We present the verbal report and the electroencephalographic (EEG) alpha profile of a female participant scoring a maximal 34 on the Absorption Scale, recorded before and while she was immersed in a whole-body perceptual deprivation (WBPD) tank. We analyze her trancelike experience in terms of the imagery reported: a (...) spaceship, corridors, doors, a man dressed in white, speaking to God, the sun, supernova, concentric images, and an out-of-body experience. Her report is indicative of a spiritual experience, given that she felt that she was “meeting God” in the laboratory. She exhibited both frontal and parietal left > right alpha power asymmetry at baseline, whereas in the WBPD condition, there was a global increase in alpha power and especially a sharp increase in right-frontal alpha power. Her verbal report and EEG alpha profile were compared to those of another female participant, also scoring high on absorption, whose verbal report was also indicative of a trancelike experience. For further comparison, we present the data for two participants scoring low on absorption. Spiritual experience that can be verbalized might be associated with a marked increase in right-frontal alpha power, as reported here. In contrast, a mystical experience characterized by ineffability would be indicated by a marked increase in left-frontal alpha power. (shrink)
