Non-deliberate perversity-A type of Mithyātva (perverse faith);
that world-view, on account of which, false metaphysical doctrine is adhered to, not deliberately insisting on it.
anābhigrahikaṃ tu prākṛtalokānāṃ sarve devā vandanīyaḥ, na nindaniyāḥ, evaṃ sarve guravaḥ sarve dharmmāḥ.
(Yośā 2.3 Vṛ Pa 165)
