Vritra in the context of "Vajra"

Indrani (Sanskrit: इन्द्राणी, IAST: Indrāṇī), also known as Shachi (Sanskrit: शची, IAST: Śacī), is the queen of the devas in Hinduism. Described as tantalisingly beautiful, proud and kind, she is the daughter of the asura Puloman and the consort of the king of the devas, Indra.

According to legend, due to her heavenly beauty and sensuality, Indrani was desired by many men, many of whom tried to marry her. When Indra was away performing his penance for the slaying of Vritasura, Nahusha, a mortal king of the Lunar dynasty, was chosen as the ruler of the heaven. The latter tried to seduce Shachi and make her his queen, though she cleverly executed a scheme to dethrone him and later reunite with her husband.

Indra (/ˈɪndrə/; Sanskrit: इन्द्र, IPA: [in̪d̪rɐ]) is the Hindu god of weather, considered the king of the devas and svarga in Hinduism. He is associated with the sky, lightning, weather, thunder, storms, rains, river flows, and war.

Indra is the most frequently mentioned deity in the Rigveda. He is celebrated for his powers based on his status as a god of order, and as the one who killed the great evil, an asura named Vritra, who obstructed human prosperity and happiness. Indra destroys Vritra and his "deceiving forces", and thereby brings rain and sunshine as the saviour of mankind.

Asuras (Sanskrit: असुर) are a class of beings in Indian religions. They are described as power-seeking beings related to the more benevolent Devas (also known as Suras) in Hinduism. In its Buddhist context, the word is translated as "titan," "demigod," or "antigod".

According to Hindu texts, the asuras are in constant fear of 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".

A sea serpent is a type of sea monster described in various mythologies and religious texts, most notably Mesopotamian (Tiamat), Ugaritic (Yam, Tannin), Judaic (Leviathan, Rahab), ancient Greek (Cetus, Echidna, Hydra, Scylla), Vedic (Vritra,Surasa) and Norse (Jörmungandr).
