Humans consist of complex physical materials. However, we determine and experience our lives through numerous spiritual moments. Should consciousness be described as an outcome of physical matter and senses, or is it a higher mental construction?
What is consciousness? Hm! Sounds like dangerous waters to attempt to navigate, but, anyway, here goes;
Consciousness, at least within a psychological frame seems to always include an aspect of self-awareness. But even taken together these two conceptions have not seemed to logically lead anywhere useful. That is primarily because different interpretations of what it means to be aware of self just lead into differing types of argument which never seem to go anywhere other than in concentric circles. So here is a quite different path or at least a suggested path to unraveling this persistent 'Gordian knot'
Spinoza in his "Ethics" Part Three- Of the Affects [Emotions] in Propositions 6-7-8, introduces, what he considers to constitute the essence of human nature, he termed it 'conatus' or 'striving'. It has been defined as 'self-assertive impulse', 'desire'/'appetite' and 'agency-in-act'. Taken together these three designations indicate the nexus where the urge to continue in existence merges with the desire to accumulate the necessary security and products required and the capability and intelligence to problem solve and join with other like-minded people to form communities to accomplish these ends.
The bodily mechanism operating through this 'conatus' receives impressions from objects/people in the environment [today we would term these digital signals]. These impressions instantaneously convert into 'emotional triggers' which automatically and ceaselessly bombard the brain with inputs which it stores. These data are then 'taken under consideration' by the mind which sorts, analyzes and converts into 'ideas'. Some of these 'ideas' become 'adequate' or clearly understood. Others, which cannot be deciphered remain 'inadequate'. The function within the mind which performs this evaluation consists in a combination of 'reflective knowledge' [observing, measuring and comparing past experience with the data and 'intuitional understanding' [let's leave that for the moment].
This then, while not a modern explanation of consciousness is one that may, just may, be deserving of consideration.

Since there is cosmic consciousness, it is not worth dealing human consciousness separately. You know, even the answers to many questions regarding death is still completely unknown. The same will be the case of consciousness also. This is because of that great cosmic consciousness. We can never deny the fact that even in unicellular organisms like bacteria and viruses have consciousness. Then you can make sure that consciousness has no relation to the number of cells or its complexity. Consciousness is everywhere; in animate objects, inanimate objects, tangible, intangible and everywhere.

He who can look into himself realizes this Truth. When he realizes it, he knows his consciousness is everywhere and everything ( https://www.speakingtree.in/allslides/sarvam-khaluidam-brahma )...and he attains liberation from all bondage. Now you may think about: "What happens to consciousness even if his body becomes no more?"
