Asuras (Sanskrit: असुर) are a class of beings in Indic religions. They are described as power-seeking demons related to the more benevolent Devas (also known as Suras) in Hinduism. In its Buddhist context, the word is sometimes translated "titan", "demigod", or "antigod". According to Hindu scriptures, the asuras are in constant battle with the devas. Asuras are described in Indian texts as powerful superhuman demigods with good or bad qualities. In early Vedic literature, 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 their 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". Asuras are part of Hinduism along with Devas, Yakshas (nature spirits), Rakshasas (fierce man-eating beings or demons), Bhutas (ghosts) and many more. Asuras have been featured in many cosmological theories and legends in Hinduism and Buddhism. Asura is a given name by Devas to other races collectively as Asura means not-sura , where sura is another name for Devas. 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". The 5th century Buddhist philosopher, Buddhaghosa explains that their name derives from the myth of their defeat at the hands of the god Śakra. According to the story, the asura were dispossessed of their state in Trāyastriṃśa because they became drunk and were thrown down Mount Sumeru.
