The GENERAL CONTEXT of such use is:
density:
Density is one of the 'elements' of Corporeality's 'interface' with Incorporeality. According to the QUFD Formulation:

Temperature - as we all know, within the "dimension" of human-entity-existence (of the Universal/Cosmic scale/range of possibilities of existence, of all Sentience), is 310.15 K, or 98.6 F. If the temperature is anything else, from the infinitely cold to the infinitely hot, we are then talking about a completely different dimension of Sentience-consciousness - NOT of humanity! Of course, density and Spirit must also pertain, to further define such OTHER dimensionality of Sentience.

Density - according to those scientists of the Quantum who have so "specified" such (in current secular research as well as non-secular research), is (-)minus 120 decimals of condensate (however referenced). Of course, such a "measure" is so infinitesimally microscopic (and quantum), that it is, as yet (with modern technology), unmeasurable (as is, likewise, the "density" of those quantum axion particles of those "dimensions" of consciousness which pervade the Cosmos - commonly called the cosmic "dark matter"). Again, if we are referring to any other "measure" of density, we are, again, talking about a completely different dimension of Sentience-consciousness - NOT of humanity. Infinitely smaller densities to infinitely larger densities pertain to other NON-human Sentience-consciousness, ranging from the quantum particles, such as leptons, to amoebas, to ants, to trees, to rocks, to the biosphere, to a planet, to a pulsar, to a galaxy, and on to Infinite Consciousness Him/HerSelf. Again, temperature and Spirit must also pertain to such other dimensions of consciousness. Spirit - and the quantum axion particles thereof, which infuse and pervade the Cosmos, IS the controlling (or supervising) factor here, as to the human brain/mind INTERFACE of which we are noting herein this Formulation (and since we are NOT including nor defining Spirit, IN THIS DOCUMENT, as the "infusion", or Sentience factor for NON-human Sentience - which it certainly IS, I leave such to be defined by other scientists of the Quantum)

Such is the 'statement' from the original QUFD Formulation. What needs to be clarified here, is the exact point-location to which this is referring to, which is the glial nucleus, the 'interface point' between Incorporeality and Corporeality. This applies to both the Density and the Temperature, at this 'interface point', in that the two 'specifications' given are for the human 'interface' between Brain and Mind, for Consciousness/Incorporeality, in that such 'specifications' cannot apply directly within Incorporeality, where these two 'elements' do not exist! Only Spirit, in the form of the quantum axion particle, exists within Incorporeality! The other two 'elements' exist only at the 'interface', but are yet Corporeal!
