Believer in uselessness of knowledge - A heretic philosopher who, repudiating knowledge as the means of attainment of the liberation, believes only in performance (of penance etc.) as its means.
Ajñānavādinastvāhuḥ - apavargaṃ pratyannpayogitvāt jñānasya. kevalaṃ kaṣṭaṃ tapa evanuṣṭheyaṃ, na hi kaṣṭaṃ vineṣṭasiddhiḥ.
(UśāVṛ Pa444)
