Bhagavad Gita · 16.7

प्रवृत्तिं च निवृत्तिं च जना न विदुरासुराः।न शौचं नापि चाचारो न सत्यं तेषु विद्यते॥

pravṛttiṁ cha nivṛttiṁ cha janā na vidur āsurāḥ na śhauchaṁ nāpi chāchāro na satyaṁ teṣhu vidyate

Those of demoniac nature do not know what action should be taken and what should be avoided. Neither purity, nor good conduct, nor truthfulness is found in them.
