Grammatical Analysis
Ahirika: [nt.] shamelessness; lack of moral conscience. Formed by negative prefix a (not/without) + hiri (moral shame).
Orthodox Definition
Ahirika is a primary unwholesome mental factor (akusala-cetasika). Along with its twin anottappa (moral recklessness), it is classified as a universal unwholesome factor (sabbākusalasādhāraṇa), meaning it arises in absolutely every single unwholesome state of mind without exception.
It represents the complete absence of internal self-respect. While a wise person shrinks away from evil out of dignity, a person afflicted by ahirika feels no internal disgust or hesitation when engaging in physical, verbal, or mental misconduct.
The Atthasālinī compares this mental factor to a village pig that feels absolutely no disgust in eating filth. Because it removes the internal braking system of the mind, ahirika allows greed, hatred, and delusion to manifest into heavy, destructive physical actions.
