इन्द्रस्य नु वीर्याणि प्र वोचं यानि चकार प्रथमानि वज्री ।
अहन्नहिमन्वपस्ततर्द प्र वक्षणा अभिनत्पर्वतानाम् ॥१।।
अहन्नहिं पर्वते शिश्रियाणं त्वष्टास्मै वज्रं स्वर्यं ततक्ष ।
वाश्रा इव धेनवः स्यन्दमाना अञ्जः समुद्रमव जग्मुरापः ॥२।।

1. Now I shall proclaim the heroic deeds of Indra, those foremost deeds that the mace-wielder performed: He smashed the serpent. He bowed out the waters. He split the bellies of the mountains.
2. He smashed the serpent resting on the mountain — for him Tvaṣṭar had fashioned the resounding [sunlike] mace. Like bellowing milk-cows, streaming out, the waters went straight down to the sea.

— Rigveda, 1.32.1–2

In the Brahmavaivarta Purana, Indra defeats Vritra and releases the waters. In post-Vedic texts, Indra’s importance declines, and he evolves into a minor deity in comparison to others in the Hindu pantheon, such as Shiva, Vishnu, or Devi. In Puranic mention, he becomes a source of nuisance rains sent out of anger with an intent to hurt mankind and Krishna as an avatar of Vishnu, comes to the rescue by lifting Mount Govardhana on his fingertip, and letting mankind shelter under the mountain till Indra exhausts his anger and relents. In the post-Vedic period, he rides a large, four-tusked white elephant called Airavata. The Sangam literature also describes Indhira Vizha (festival for Indra), the festival for want of rain, celebrated for one full month starting from the full moon in Chitrai and aspects of Indra as a deity are cognate to other Indo-European gods; they are thunder gods such as Thor, Perun, and Zeus who share parts of his heroic mythologies, act as king of gods, and all are linked to “rain and thunder”.
