That understanding which considers irreligion to be religion and religion to be irreligion, under the spell of illusion and darkness, and strives always in the wrong direction, O Pārtha, is in the mode of ignorance.

18.32. The intellect which, containing darkness (ignorance), conceives the unrighteous one as righteous and all things topsy-turvy-that intellect is deemed to be of the Tamas (Strand).

18.32 And that which, shrouded in Ignorance, thinks wrong right, and sees everything perversely, O Arjuna, that intellect is ruled by Darkness.

18.30-32 Pravrttim etc. upto Tamasi mata. Incorrectly ; not properly.

18.32 That Buddhi is of the nature of Tamas which is 'enveloped in Tamas' and 'reverses every value.' The meaning is that it regards Adharma as Dharma and Dharma as Adharma, existent as non-existent, and non-existent as existent, and higher truth as the lower and the lower truth as the higher, and thus reverses every value.
