Vrta is not considered an asura or demon, and there is no mention of Danu or the danavas at all.

Demons are sometimes depicted as ancestral, deceased beings who had been mistreated in their human lifetime by relatives who had not performed the proper and correct funeral rites for these beings in their human form. Physical appearance The daityas and the danavas share the same physical features and characteristics as their counterparts, the devas. In Hindu religion, the power of Maya or the power of illusion is possessed by both good and evil supernatural beings. The power of illusion allows beings to change their physical form. Despite their extensive role in certain texts, there are not many examples of the physical characteristics of the danavas in their own right or even in conjunction with devas in literature and art.

Both good and bad supernatural beings demonstrate malevolent, powerful, yet merciful personalities. Therefore, at times, it is difficult to discern between the roles of oppositional beings. This is particularly evident in earlier Vedic literature where there is not an emphasis on the oppositional qualities of these beings. In many myths or hymns, they perform identical actions to one another. Subsequently, the danavas's role is hardly distinguished or mentioned in Vedic literature. O'Flaherty and Doniger state that in later literature like the Mahabharata, these beings are slowly considered a part of "... two separate castes; each has his own job to do – the gods to encourage sacrifice, the demons to destroy it – but there is no immorality in the demons; they are merely doing their job, a destructive one..." While, in the earlier Vedic period, themes of caste-based structures of worship were not prominent. Myths Natyashastra In the Natyashastra, the danavas are depicted as evil demons, meddling with dancers. Particularly, in the first chapter of the Natyashastra, the danavas freeze and stop the performance of the dancers during an important event dedicated to the Hindu deities. Angering the
