Asuras

Asuras (Sanskrit: असुर) are mythological lord beings in Indian texts who compete for power with the more benevolent devas (also known as suras). Asuras are described in Indian texts as powerful superhuman demigods or demons with good or bad qualities. The good Asuras are called Adityas and are led by Varuna, while the malevolent ones are called Danavas and are led by Vritra. In the earliest layer of Vedic texts Agni, Indra and other gods are also called Asuras, in the sense of them being "lords" of their respective domains, knowledge and abilities. In later Vedic and post-Vedic texts, the benevolent gods are called Devas, while malevolent Asuras compete against these Devas and are considered "enemy of the gods" or demons.

Asuras are part of Indian mythology along with Devas, Yakshas (nature spirits) and Rakshasas (ghosts, ogres), and Asuras feature in one of many cosmological theories in Hinduism.

Monier-Williams traces the etymological roots of Asura (असुर) to Asu (असु), which means life of the spiritual world or departed spirits. In the oldest verses of the Samhita layer of Vedic texts, the Asuras are any spiritual, divine beings including those with good or bad intentions, and constructive or destructive inclinations or nature. In later verses of the Samhita layer of Vedic texts, Monier Williams states the Asuras are "evil spirits, demons and opponents of the gods". Asuras connote the chaos-creating evil, in Hindu and Persian (Arians) mythology about the battle between good and evil.

Bhargava states the word, Asura, including its variants, asurya and asura, occurs "88 times in the Rigveda, 71 times in the singular number, four times in the dual, 10 times in the plural, and three times as the first member of a compound. In this, the feminine form, asuryaa, is included twice. The word, asurya, has been used 19 times as an abstract noun, while the abstract form asuratva occurs 24 times, 22 times in each of the 22 times of one hymn and twice in the other two hymns".

Asura is used as an adjective meaning "powerful" or "mighty". In the Rigveda, two generous kings, as well as some priests, have been described as asuras. One hymn requests a son who is an asura. In nine hymns, Indra is described as asura. Five times, he is said to possess asurya, and once he is said to possess asuratva. Agni has total of 12 asura descriptions, Varuna has 10, Mitra has eight, and Rudra has six. Bhargava gives a count of the word usage for every Vedic deity. The Book 1 of Rig Veda describes Savitr (Vedic solar deity) as an Asura who is a "kind leader".
