Bhagavad Gita · Chapter 16: The Divine and the Demonic Natures
Bhagavad Gita 16.7
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 ||
People of demonic nature do not know what should be done and what should not. There is no purity in them, no good conduct, and no truth.
Modern context
The first mark of the demonic: they do not know what to do and what not to do. They have no inner compass. Without a sense of right and wrong, there is no purity, no good conduct and no truth. This is not mainly about lack of information. It is about not caring to ask the question at all, acting only on impulse.
