The hard problem
David Chalmers drew a line between what he called the 'easy problems' of consciousness — explaining perception, attention, memory, learning; describing how the brain processes information and produces behaviour — and the 'hard problem': why any of it feels like anything. You can describe every neural correlate of seeing red without explaining the redness itself. You can map every process involved in pain without explaining why it hurts. All the easy problems are problems of function; the hard problem is about the what-it-is-like. The problem is hard not because we lack data but because no quantity of physical description seems to touch the experiential fact.
The contemplative inversion
The Advaita Vedānta tradition inverts the scientific framing entirely. Where neuroscience asks how does matter produce consciousness?, Advaita asks what is the evidence that consciousness is a product of matter? The recognition pointed to by Ramana Maharshi, Nisargadatta Maharaj, and — in the contemporary West — Rupert Spira is that consciousness is not the output of the brain but the field in which the brain, and all its neural processes, appear. I Am That and Being Aware of Being Aware are the most sustained English-language presentations of this position. The immediate implication is that the hard problem dissolves: nothing produces consciousness; consciousness is what is prior to the question.
Where it shows up in practice
Every serious meditation practice eventually reaches the question of who or what is doing the meditating. Adyashanti's Do Nothing asks practitioners to stop all effort and observe what remains — which is the question of what consciousness is when it is not directed at an object. How Do I Move From Intellectual Understanding to Lived Knowing addresses the gap between understanding that consciousness is primary and the understanding living in the body. Jon Kabat-Zinn's MBSR does not use this vocabulary at all, but the strengthened 'observer' that mindfulness training produces is a functional approximation of what Advaita means by the witness — a preliminary station on the same inquiry.
What it isn't
Consciousness is not the brain, though it correlates with brain activity in ways that are now extensively documented. It is not attention, not intelligence, not cognition, not awareness in the ordinary sense — these are all objects or functions that arise within consciousness; they are not consciousness itself. It is not a substance, a location, or a quality of certain complex systems, though all of these framings have been proposed. Whether it is fundamental, emergent, or simply our current name for something we do not yet understand — genuinely, this remains open.
