Prabhupāda:
- dvau bhūta-sargau loke 'smin
- daiva āsura eva ca
- daivo vistaraśaḥ prokta
- āsuraṁ pārtha me śṛṇu
- (BG 16.6)
Bhagavān, Śrī Kṛṣṇa, is addressing Arjuna as. . . Sometimes He addresses him as Bhārata, "the descendant of the Bharata dynasty," and sometimes He addresses him as Pārtha, and sometimes He addresses him Dhanañjaya, His friend. This time He addresses him as Pārtha. Pārtha means his mother's name was Pṛthā. From Pṛthā, the word Pārtha comes. His mother happened to be Kṛṣṇa's father's sister. So very intimately and friendly, He addresses him as Pārtha, "My dear son of My aunt." That means, "We have got very intimate relationship. Not only we are friends, but we have got family relationship. So therefore I am speaking you about the truth, that there are two classes of living beings." Two classes of living beings, dvau. Dvau means two. One class is called daiva, or divine, divine nature, and the other class is called demonic nature, āsura.
So in Viṣṇu-Purāṇa there is also reference to this context, where it is said,
- dvau bhūta-sargau loke 'smin
- daiva āsura eva ca
- viṣṇu-bhakto bhaved daiva
- asuras tad-viparyayaḥ
Daiva means generally viṣṇu-bhakta. Viṣṇu means the Supreme Lord who is all-pervasive. Everywhere He is present. Kṛṣṇa, the Supreme Lord, He is Viṣṇu also in His Paramātmā feature. Kṛṣṇa has got three features: brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11). Kṛṣṇa, the Absolute Truth, is known in three features or three angle of visions. One is Brahman, all-pervasive Brahman. Sarvedam akhilaṁ jagat. So Brahman means His effulgence, bodily rays.
