Does Consciousness explain Reality?

My experience of Reality is three-fold: physical, mental, and ephemeral. Relatively few humans are likely to have had exposure to the ephemeral (spiritual) realm. This realm is both exciting and confusing.

Among the multiple facets of the inter-connections between these 3 realms is this issue: Is there an over-arching, all-encompassing, dimension into which all these 3 realms fit? Notwithstanding the apparently challengeable conclusion from the Michelson-Morley experiment (a very long time ago), is there something referred to as the aether which could provide an operational basis for illuminating these 3 realms operating in unison?

Interestingly, there are a number of scientists researching the aether. They are obviously working beyond the prevailing explanatory paradigms of science. I hasten to add that I accept the usefulness and reliability of the scientific method. However, it is necessarily limited to the mechanistic material realm of experience. It may, however, be useful in illuminating the mental realm – or parts thereof. It could not, under any circumstances, assist in perusing the mysteries of the spiritual realm. Beware (as someone wrote) vivisecting the songbird to identify the source of its trill.

My question about an over-arching dimension arose from my reading of Easwaran’s translation of the core Upanishads. Hinduism’s Upanishads offer a view of Reality through spirituality – not available at an equivalent depth from other religions. This is not surprising in view of its distant origins in time. The Vedas, their precursor, seemingly originated about 7,000 BC (dated by tracing a unique planetary configuration).

Hindu cosmology is complex, and allegedly inherited (but that is a separate issue). Human history before the Universal Flood (of about 11,000 BC) is uncertain – possibly covered in mud.

The relevance here of Hindu cosmology is the concept of Consciousness, and its role. Consciousness is posited as ever-existing, all-embracing, all-pervasive – like the aether. It is an un-caused First Cause.

In relation to my posts about the mind and the human soul, were our minds and souls to exist outside our bodies in some ephemeral (cloud) form (like information on the Internet), could they not be associated with (linked to, or part of) an all-pervasive Consciousness?

Furthermore, since everything in the Cosmos appears to be inter-connected, could that be explained by an all-embracing Consciousness (like a gossamer blanket which covers everything)?

Thus, the physical, mental and ephemeral realms of my experience may represent my awareness of a 3-tiered Reality reflecting an ever-existing Consciousness. That is, could Consciousness create and sustain all that is, in spite of not being adequately explicable to humans?

(Disclaimer: In this life I am a Hindu. In my previous life it appears that I have been a Muslim in Central Asia. Way deep in me is a memory of being a Jew in the Middle East. I have also been a Christian. As a free-thinker, I merely seek understanding of the place of humanity in the Universe. I have no axe to grind. My tentative beliefs and speculations are just what they are.)
