Bhagavad Gita 9.12

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

मोघाशा मोघकर्माणो मोघज्ञाना विचेतसः।
राक्षसीमासुरीं चैव प्रकृतिं मोहिनीं श्रिताः॥

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