THE SIGNS OF MEDITATION PROGRESS (PDF-2084)

Meditation and dharma practice are about becoming more aware, but aware of what? 

Ultimately (as the Tibetan Buddhists tell us) we seek to become aware of the true nature of the mind, whatever that is. If we have to ask then we don't know; that's what we have yet to find out. However, between that and where we are today is a sea of our own endless thoughts and obscurations, literally everything standing between our current state and realizing the unobstructed nature of the mind. That's why we practice.
