Bhagavad Gita 9.12

मोघाशा मोघकर्माणो मोघज्ञाना विचेतसः।राक्षसीमासुरीं चैव प्रकृतिं मोहिनीं श्रिताः॥

moghāśā moghakarmāṇo moghajñānā vicetasaḥ |rākṣasīmāsurīṃ caiva prakṛtiṃ mohinīṃ śritāḥ ||

They are possessed of the deceitful nature of demons and undivine beings, filled with vain hopes, vain actions, and vain knowledge that is senseless.

Their hopes are futile, their actions worthless, their knowledge ineffective; they are without sense, deceitful, barbaric, and godless.

Our plain-language meaning of this verse is waiting for scholar review.
