Bhagavad Gita Chapter 16, Verse 6

द्वौ भूतसर्गौ लोकेऽस्मिन्दैव आसुर एव च | दैवो विस्तरशः प्रोक्त आसुरं पार्थ मे शृणु ||

dvau bhūta-sargau loke 'smin daiva āsura eva ca daivo vistaraśaḥ prokta āsuraṁ pārtha me śṛṇu

In this world, there are two types of created beings—the divine and the demoniac. The divine has been described at length; hear from Me, O Arjuna, about the demoniac.

Krishna establishes the framework: 'dvau bhūta-sargau'—two types of created beings exist in this world. 'Daiva'—divine, 'āsura'—demonic. These aren't separate species or fixed categories—they're qualities that exist in all beings. You can have divine qualities or demonic qualities, or both. Krishna notes: 'daivo vistaraśaḥ prokta'—the divine has been described at length (in verses 16.1-16.3). Now: 'āsuraṁ pārtha me śṛṇu'—hear from Me about the demonic. This verse sets up the deeper exploration of demonic nature that follows. Krishna is about to explain not just what demonic qualities are, but how they manifest, how they think, what they believe, and where they lead. Understanding both is essential: you need to know what to cultivate and what to avoid.
