Observation of galaxies that are rotating too fast to be held together by the gravity of their visible matter or should not have formed or move as they do has led many astronomers to hypothesize the existence of so-called "dark matter." They do not know what it is because the Standard Model of particle physics provides no clues to its identity. All that they can be certain about is that it is invisible but exerts sufficient gravitational force to stop galaxies being pulled apart by their centrifugal forces. The author proposes that it is mostly the E₈-singlet sector of E₈×E₈′ heterotic superstrings, or what henceforth will be referred to as "shadow matter." Just as the two chiral, subquark states of the E₈′-singlet sector (ordinary matter) were described over a century ago by the Theosophists Annie Besant and C.W. Leadbeater, using a yogic siddhi, or paranormal ability, with the Sanskrit name of anima, so the fundamental constituents of shadow matter making up most of dark matter were, likewise, discovered and described by Ronald D. Cowen, a Canadian Buddhist and science teacher. This faculty of remote-viewing on the microscopic scale has been named "micro-psi" by the author. Cowen suddenly acquired this faculty (as well as other minor siddhis) after achieving in 1979 the so-called "Arahat  breakthrough" through many years of advanced, Buddhist meditation under the guidance of Namgyal Rinpoche, his spiritual teacher. This is described in his book "The Path of Love" (FriesenPress, 2015). The paranormal ability to magnify very small objects is described in verse 44 of the Uttara Tantra, a highly revered, Mahayana Buddhist text:

"The essence of Buddhahood at fruition has the
qualities of clear cognition, jnana, and freedom from
impurities. The quality of clear cognition has five
powers relating to the variety of phenomena. The first
power of clear cognition is 'divine vision,' which is the
ability to see extremely distant and small things..."

The following pages provide evidence supporting Cowen's discovery in the form of examples of sacred geometries that embody the various structural parameters of a basic (as yet undiscovered) subatomic particle that he claimed makes up an invisible kind of matter pervading the universe — or, rather, a universe that coexists with the familiar one yet is separate from it in a dimensional sense. Instead of the exotic flotsam and jetsam conjectured by theoretical physicists and astrophysicists to account for dark matter, Cowen's micro-psi observations imply the existence not of different states of ordinary matter that conform to the Standard Model but of entirely new forms of matter undescribed by this incomplete model that are as equally fundamental as atoms and their nuclei and more prevalent throughout the universe, being responsible for about 85% of its matter. Flying in the face of the orthodox, scientific presupposition that consciousness is an epiphenomenal product of neuronal activity in the brain, Cowen realised that he had been observing with micro-psi energy/information transfers in molecular counterparts of this invisible biomatter that are totally unknown to science because their gravitational forces are detectable only on the galactic scale of dark matter. According to Cowen, these complex processes serve as the basis of the mind/body interaction. Neuronal activity is merely the end product of these exchanges of energy/information between highly organised groups of particles that behave according to the laws of physics of another universe, namely, the invisible universe of shadow matter (the E₈-singlet sector of E₈×E₈′ heterotic superstring theory). It is shown in this section to be part of the same, universal blueprint embodied in certain sacred geometries that shapes the particle, as yet undiscovered by particle physics, composing the so-called "up" and "down" quarks that the author's research indicates were remote-viewed 127 years ago by Besant & Leadbeater (see here and here).
