Ultimately, there is no such thing as "my consciousness," but just the one consciousness and to sense your connectedness with the one (I can sense that continuously, which is why I can say that I know this for sure) to sense that connectedness with the one consciousness that pervades the universe, which in some traditions is called God, to sense that frees you of fear, from anxiety, and takes you to a very deep place of peace, but also of heightened aliveness.
Eckhart TolleWhen you continuously know and sense yourself as the space of consciousness rather than what appears in consciousness - sense perceptions, thoughts, emotions - then it can be said that you are enlightened... except that you wouldn't think or speak of yourself as 'enlightened', because that would instantly create another mind-based conceptual identity and so it would be the end of 'your' enlightenment.
