Consciousness is that which interacts and experiences itself in all ways imagined through form.
Consciousness is the only thing that can fundamentally exist and can have experiences. All experiences that anyone has can only be experienced within Consciousness.
Consciousness can only experience itself through the process of self-reflection, you cannot experience anything outside of your Consciousness.
You cannot have an experience of anything other than YOU (as Consciousness). The external world is merely a mental construct (projection); focal points of consciousness created and imposed from your internal (subjective) reality.
Everything you see and experience are nothing but mirrors of yourself that simply reflect back to you in order to give you subject/object experiences (relationships).
