The GENERAL CONTEXT of such use is:
cosmic duality:
I've already explained how one's personal 'reality' is also a 'cosmic duality'! (See the previous Definition in this Dictionary, 'corporea'.)

A cosmic duality can actually be any Condensate Of Incorporeality which is paired with its 'twin' Condensate of Corporeality as a Life-form of some kind, whether human, ant, rock, tree, planet, galaxy, pulsar, molecule, quark, electron, or any of the quantum forces, fields and gravity, all of which have their 'twin', as the 'cosmic duality' of themselves, which exists there, on the 'other side of the Fence', within Incorporeality!

Also, as explained in detail in my latest Book (see the bottom of this page), the Universe itself (and all Universes!) has its own cosmic 'twin'! All of the physical, material 'stuff' (All That Is!), exist within a Condensate of Corporeality that is the Physical Universe. But there, on the 'other side of the Fence', is the glowing incandescence of the Universe's 'twin', which is its Consciousness, Mind, Spirit and Sentience!

Of course, within Incorporeality, we can also have cosmic dualities, such as God (Infinite Consciousness) versus Lucifer, or the Luciferian Complex of Consciousness and 'Reality'! However, these 'dualities' are all Incorporeal!

In other words, the Incorporeal regions and realms of Consciousness can also have various 'dualities' within and without of those realms as well, that are not corporeal-incorporeal 'dualities' but are exclusively incorporeal only! I am not going to discuss these Higher (or Lower) Realms here!
