Chapter 16 · Divine and Demonic Natures · Krishna said
Bhagavad Gita 16.7 — Confusion of the demonic
प्रवृत्तिं च निवृत्तिं च जना न विदुरासुराः। न शौचं नापि चाचारो न सत्यं तेषु विद्यते ॥
pravṛttiṃ ca nivṛttiṃ ca janā na vidurāsurāḥ | na śaucaṃ nāpi cācāro na satyaṃ teṣu vidyate ||
Meaning
People of demonic nature do not know what to do and what to avoid. There is no purity, no good conduct and no truth in them.
