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 Abhidhammatthasaṅgaha 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.
Quote
Tattha gūthato gāmasūkaro viya kāyaduccaritādito ajigucchanalakkhaṇaṃ ahirikaṃ, aggito salabho viya tato anuttāsalakkhaṇaṃ anottappaṃ.
Among these, ahirikaṃ is characterized by not being disgusted by evil actions of body, etc., like a village pig is not disgusted by filth. Anottappaṃ is characterized by not being afraid of such actions, like a moth is not afraid of fire.Tenāhu porāṇā –
Therefore, the ancients said:‘‘Jigucchati nāhiriko, pāpā gūthāva sūkaro;
“The shameless one is not disgusted by evil, just as a pig by filth;Na bhāyati anottappī, salabho viya pāvakā’’ti.
The undaunted one fears not, like a moth before a flame.”— Abhidhammatthasaṅgaha (Chapter II, Cetasikavibhāgo)
