Grammatical Analysis
Bhayañāṇa: [nt.] Knowledge of fearfulness; knowledge of terror. Formed by bhaya (fear, terror, fright) + ñāṇa (knowledge).
Orthodox Definition
Following the direct vision of the continuous dissolution of reality (bhaṅgañāṇa), the meditator naturally experiences Bhayañāṇa. Having seen that all formations in the past have ceased, all present formations are ceasing, and all future formations will cease, the three realms of existence (sense-sphere, fine-material, and immaterial) appear intensely fearful.
This is not a worldly, panicked emotion or clinical anxiety. It is a profound, serene, philosophical terror—an objective realization that there is absolutely no safety, security, or refuge to be found anywhere within the conditioned cycle of saṃsāra, as the entire structure is continuously crumbling.
