Chapter XVI · Śloka 6
द्वौ भूतसर्गौ लोकेऽस्मिन्दैव आसुर एव च ।
दैवो विस्तरशः प्रोक्त आसुरं पार्थ मे शृणु ॥
dvau bhūtasargau loke 'smin daiva āsura eva ca |
daivo vistaraśaḥ prokta āsuraṃ pārtha me śṛṇu ||
There are two types of beings created in this world — the divine and the demoniac. The divine has been described at length; hear from Me now about the demoniac, O Pārtha.
Krishna frames the chapter's structure: the divine has been elaborated; now the demoniac nature will be examined in detail so Arjuna — and the reader — can recognise and avoid it. The binary is cosmological, not merely moral.
