Because consciousness itself has no material reality, it cannot be experienced objectively, only imperienced directly within our own being. Imperience is how we sense conscious awareness and awaken intuitive insight into the dharma (truth) of nonduality and the very heart of consciousness.
We regard profoundly wholesome qualities like love, compassion, and moral conscience as matters of the heart, and when they are awake in us, we imperience them throughout our body and being. The depths of these feelings reflect their source in divine consciousness, which we are able to sense most directly and personally in our blood—independent of our brain. Because our blood is most concentrated in our chest, this is where we feel love and empathy most prominently, and why we consider these qualities to be matters of the heart.
Our personal consciousness awakens from the inside out, from firsthand imperience within our own blood and being.
