Eventually with the practice of meditation and other types of yogas, the mind becomes more subtle. The understanding of the nature of consciousness as free from outer perception (of physical objects) as well as internal perceptions (dreams, visions, other mental experiences) can then start to emerge. Once the independent nature of consciousness (free from all perceptions) is understood, one can recognize the essential quality of existence and pure being in the midst of various experiences.
When attention/awareness become self-focused, that is called Self-Inquiry. When attention lights up attention, awareness lights up awareness, consciousness lights up consciousness, Self is Realized as Sat-Chit-Ananda, the ultimate subject, the very core of being. Sri Ramana called it simply the Heart, whose nature is that of silence which is beyond all understanding.
