Hypnotic rehearsal utilizes attentional hyperacuity
, loosened reality-testing, suspension of disbelief, and enhanced capacity for fantasy.
Continuing with the project, the program, of investigating the purported ability of virtuoso , Indo-Tibetan practitioners of "yogic directly perception of the limits of phenomena," the "partless particles" of that which exists; our framework suggests that the intensive focus on developing the technical ("soft tissue-high tech") means to do so, is based on what in contemporary cosmopolitan neuroscientific terms are principles recently established, namely neuroplasticity-mediated perceptual learning in the direction of hyperacuity, the "remarkable" (in Princeton biophysicist William Bialek's words) human capacity to perceive distances within the range of a fraction of the diameter of a photoreceptor cell, ie within the range of millionths of a meter.
Furthermore, relevant to our thesis in this context is the idea that the practice of mandala meditation, according to a large body of indirect but highly relevant data from the field of "environmental enrichment," is likely to trigger stem cell activation in the brain, neurogenesis (see Bushell 2001, 2005), which in turn would likely be associated with neuroplastically-mediated perceptual learning in the direction of the enhancement of the capacity for hyperacuity.
Returning to consideration of the claims of the tradition of Indo-Tibetan Kalachakra Mandala practice, we can already appreciate the potential range of human visual capacities, in terms not only of least light perception, but also of hyperacuity, eidetic imagery and memory, and subitizing, before continuing to consider the claims of that tradition.
In our attempt to develop a model based on potential parallels and homologous types of perceptual phenomena in the fields of neurology, anomalous psychology, etc, we may then now add to the capacities for eidetic imagery and subitizing, that of hyperacuity. For the size of a mustard seed is 1-2 millimeters in diameter, and hyperacuity as defined above refers to the ability to accurately perceive phenomena within the range of millionths of a meter, so this feat is still hypothetically within the range of possibility; creating this testable hypothesis within the interdisciplinary, cross cultural, anomalous psychological/psychophysical framework presented here.
