Indra

Indra (; Sanskrit: इन्द्र, IPA:) is the Vedic god of weather, considered the king of the devas and the realm of 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. Indra's significance diminishes in the post-Vedic Indian literature, but he still plays an important role in various religious accounts. He is depicted as a powerful hero.
According to the Vishnu Purana, Indra is the title borne by the king of the gods, which changes every Manvantara – a cyclic period of time in Hindu cosmology. Each Manvantara has its own Indra and the Indra of the current Manvantara is called Purandhara.
Indra is also depicted in Buddhist (Pali: Indā) and Jain texts. Indra rules over the much-sought Devas realm of rebirth within the Samsara doctrine of Buddhist traditions. However, like the post-Vedic Hindu texts, Indra is also a subject of ridicule and reduced to a figurehead status in Buddhist texts, shown as a god who suffers rebirth. In Jain traditions, unlike Buddhism and Hinduism, Indra is not the king of gods, but the king of superhumans residing in Svarga-Loka, and very much a part of Jain rebirth cosmology. He is also the one who appears with his consort Indrani to celebrate the auspicious moments in the life of a Jain Tirthankara, an iconography that suggests the king and queen of superhumans residing in Svarga reverentially marking the spiritual journey of a Jain.
Indra has similarities to various other Indo-European deities, such as Greek Zeus, Roman Jupiter, Armenian Aramazd, Germanic Odin and Thor, Slavic Perun, Baltic Perkūnas, Dacian Zalmoxis, and Celtic Taranis, part of the greater Proto-Indo-European mythology.
Indra's iconography shows him wielding his vajra and riding his vahana, Airavata. Indra's abode is in the capital city of Svarga, Amaravati, though he is also associated with Mount Meru (also called Sumeru).
