The mind affects the body and vice versa. What is their interface? From antiquity, the mind-body problem has been the quintessential issue of natural philosophy and science, as it addresses the fundamental nature of existence.
Dualism and matterism falter in addressing the mind-body problem by not being able to explain how organisms and cells which have no intelligence physiology nonetheless act intelligently. By contrast, Spokes of the Wheel cogently answers the mind-body question via energyism.
The mind cognizes Nature (the exhibition of existence) via the natural interaction of quantized coherence, which emergently formulates a physical body and associated energy system. This principle has been known as vitalism: that life is sustained via a vital energy. This quantized coherence is part of a unified field, and so permits showtivity: shared subjectivities which present the mirage of objectivity.
The human energy system has been sussed sufficiently to enable acupuncture and acupressure as efficacious medical treatments. Central hubs of the energy system – the chakras – are discernable to some (including the author, who can feel his entire energy system). Such sensitivity is common among yogi/realized beings (those in unity consciousness).
Those who would scoff at the above haven’t done their homework or are unfortunately close-mindedly obtuse – there are a lot of them about, including those with PhDs. You can’t clue the clueless, no matter how educated they get. More broadly, much of what the Collective consider knowledge is instead fiction, as inference always depends upon theory, and theories are prone to false assumptions. The conventional models and theories of cosmogony, astrophysics, quantum physics, evolutionary biology, psychology, economics, and democratic politics exemplify this point.
The under-informed may cure themselves of their factual-ignorance (fignorance) by reading Spokes of the Wheel, and eventually disabuse themselves of their perspective-ignorance (pignorance) by practicing the teachings of Ishi Nobu, which are introduced in Clarity: The Path Inside, and further elaborated in Spokes 8: The Hub of Being. The podcast show Reality & Realization and certain psychology blog entries herein are also recommended.
Living well is a discipline: an obvious statement when you consider the necessity of skill to accomplish literally anything but autonomic physiological functions. To attain the apex of living well is the ultimate skill, which requires subduing the mind through meditative practice and thereby achieving spiritual self-realization, which the supreme state of consciousness.
