The Essence of Life and the Brain-Constructed World: Consciousness, Nature, and the Experience of Liberation from the Brain-Constructed World

Human beings do not experience the world directly as it is. At the level of human experience, what we call the world emerges through the interaction of reality with sensory systems, memory, emotion, survival mechanisms, language, judgment, and the brain’s predictive processes. Through these mechanisms, the brain constructs a coherent and inhabitable world—a world necessary for survival, yet not necessarily identical to the ultimate nature of reality. This paper introduces the concept of the “Essence of Life”: a fundamental quality of being that, unlike pleasures dependent on the body, external stimuli, and the satisfaction of desire, can be experienced without acquiring anything from the external world. The Essence of Life may manifest in moments as immediate joy, vitality, beauty, lightness, and liberation. Within this framework, the Essence of Life is not produced by such moments; rather, it is understood as already present and capable of being awakened. The paper further proposes the ontological hypothesis that consciousness is not a phenomenon entirely exclusive to the human brain, but is present at different levels throughout existence, with human consciousness representing a highly complex form of it. On this basis, nature is significant not merely because of its psychologically restorative effects. Encountering nature may bring human beings into contact with forms of existence in which consciousness has not passed through the complex filters characteristic of human cognition—such as identity, narrative, psychological past, and anticipated future. Such encounters may awaken the Essence of Life within human beings. Finally, the paper distinguishes among the brain-constructed world, Observer Awareness, and the Essence of Life, and proposes that part of human suffering may arise not merely from the contents of experience, but from the complete identification of consciousness with a world constructed by the brain for survival.
