Those of demonic nature lack the ability to distinguish proper from improper action, and they know neither cleanliness, right conduct, nor truth. All eight traditions see this moral blindness as the most dangerous consequence of the demonic disposition. Shankara identifies ignorance as the root cause — without knowledge, proper conduct is impossible. Ramanuja connects this blindness to the soul's alienation from God, who is the source of moral insight. Madhva explains that without submission to divine authority revealed through scripture, the intellect becomes perverted. Abhinavagupta sees it as deeply contracted awareness that cannot perceive the ethical order flowing from universal consciousness — moral blindness is spiritual amnesia. Vallabha teaches that the Lord's presence in the heart normally guides moral intuition, but turning entirely toward illusion obscures this inner light. The bhakti tradition emphasizes that holy company and devotion restore moral clarity. Tilak warns that lack of discernment makes a person destructive in society — the active person must cultivate viveka through study. Vivekananda connects moral blindness directly to spiritual ignorance, arguing that education awakening inner divinity is the remedy. This verse diagnoses a condition, not condemns a class of people.
