1. Can you define consciousness? Or is consciousness = awareness? Is that what you meant?
2. You ask "What is the origin of awareness itself?". I really don't understand this question. What is awareness? I can't even comprehend what you mean when you ask "what is the origin of [it]?". Colloquially, physical things have "origins", which is to say that at some point some physical thing was "created" or "crafted". My intuitive idea of awareness is that it is an experience, it's not something physical.
