Varuna (; , ) is a Hindu god, associated with the sky, oceans and water. In the Vedic scriptures, he is paired with the god Mitra and is the lord of Ṛta (justice) and Satya (truth). Varuna is also mentioned as an Aditya, the sons of the goddess Aditi. In the later Hindu texts like the Puranas, Varuna is also a Dikpala or guardian of the western direction. He is depicted as a youthful man, mounted on Makara (crocodile) and holding a Pasha (noose, rope loop) and a pitcher in his hands. He has multiple wives and fathered many children, including the Vedic sage Vasishtha. He is also mentioned in the Tamil grammar work Tolkāppiyam, as Kadalon the god of sea and rain. He is found in Japanese Buddhist mythology as Suiten. He is also found in Jainism. Etymology In Hindu tradition, the theonym Váruṇa (Devanagari: वरुण) is described as a derivation from the verbal root vṛ ("to surround, to cover" or "to restrain, bind") by means of a suffixal -uṇa-, for an interpretation of the name as "he who covers or binds", in reference to the cosmological ocean or river encircling the world, but also in reference to the "binding" by universal law or Ṛta. Georges Dumézil (1934) made a cautious case for the identity of Varuna and the Greek god Ouranos at the earliest Indo-European cultural level. The etymological identification of the name Ouranos with the Sanskrit Varuṇa is based in the derivation of both names from the PIE root *ŭer with a sense of "binding" – the Indic king-god Varuṇa binds the wicked, the Greek king-god Ouranos binds the Cyclopes. This derivation of the Greek name is now widely rejected in favour of derivation from the root *wers- "to moisten, drip" (Sanskrit vṛṣ "to rain, pour"). Hindu texts Vedas In the earliest layer of the Rigveda, Varuna is the guardian of moral law, one who punishes those who sin without remorse, and who forgives those who err with remorse. He is mentioned in many Rigvedic hymns, such as 7.86–88, 1.25, 2.27–30, 8.8, 9.73 and others. His relationship with waters, rivers and oceans is mentioned in the Vedas. Rig veda 10.123 says Hiranyapaksha (golden winged bird) as the messenger of Varuna. The golden winged messenger bird of Varuna may not be a mythical one but most probably flamingos because they have colourful wings and the sukta further describes
