Manvantara in the context of "Great Flood"

A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primeval cosmic ocean which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, for example in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".

The oldest known narrative of a divinely inititated flood originates from the Sumerian culture in Mesopotamia, among others expressed in the Akkadian Atra-Hasis epic, which dates to the 18th century BCE. Comparable flood narratives appear in many other cultures, including the biblical Genesis flood narrative, manvantara-sandhya in Hinduism, Deucalion in Greek mythology, and in indigenous North American cultures.

The Vishnu Purana (Sanskrit: विष्णुपुराण) is one of the eighteen Mahapuranas, a genre of ancient and medieval texts of Hinduism. It is an important Pancharatra text in the Vaishnavism literature corpus.

The manuscripts of Vishnu Purana have survived into the modern era in many versions. More than any other major Purana, the Vishnu Purana presents its contents in Pancalaksana format – Sarga (cosmogony), Pratisarga (cosmology), Vamsa (genealogy of the gods and goddesses, sages, and kings and queens), Manvantara (cosmic cycles), and Vamsanucarita (legends during the times of various kings and queens). Some manuscripts of the text are notable for not including sections found in other major Puranas, such as those on Mahatmyas and tour guides on pilgrimage, but some versions include chapters on temples and travel guides to sacred pilgrimage sites. The text is also notable as the earliest Purana to have been translated and published in 1840 CE by HH Wilson, based on manuscripts then available, setting the presumptions and premises about what Puranas may have been.

Manu (Sanskrit: मनु) is a term found with various meanings in Hinduism. In early texts, it refers to the archetypal man, or the first man (progenitor of humanity). The Sanskrit term for 'human', मनुष्य (IAST: manuṣya) or मानव (IAST: mānava) means 'of Manu' or 'children of Manu'. In later texts, Manu is the title or name of fourteen rulers of earth, or alternatively as the head of dynasties that begin with each cyclic kalpa (aeon) when the universe is born anew. The title of the text Manusmriti uses this term as a prefix, but refers to the first Manu – Svayambhuva, the spiritual son of Brahma. In the Hindu cosmology, each kalpa consists of fourteen Manvantaras, and each Manvantara is headed by a different Manu. The current universe, is asserted to be ruled by the 7th Manu named Vaivasvata. Vaivasvata was the king of Dravida before the great flood. He was warned of the flood by the Matsya (fish) avatar of Vishnu, and built a boat that carried the Vedas, Manu's family and the seven sages to safety, helped by Matsya. The tale is repeated with variations in other texts, including the Mahabharata and a few other Puranas.

Pulastya (Sanskrit: पुलस्त्य) is one of the ten Prajapati, and one of the mind-born sons of Brahma in Hinduism. He is also one of the Saptarishi (Seven great sages) in the first age of Manu, the Manvantara.

The Thirty-three gods, or Tridasha (Sanskrit: त्रिदश, romanized: Tridaśa, lit. 'three tens'), is a pantheon of Hindu deities of the current manvantara. The Samhitas, which are the oldest layer of text in the Vedas, enumerate 33 deities classified as Devas, either 11 each for the three worlds, or as 12 Adityas, 11 Rudras, eight Vasus and two Ashvins in the Brahmanas.

Daksha (Sanskrit: दक्ष, lit. 'able, dexterous, or honest one' IAST: Dakṣa,) is a Hindu god whose role underwent a significant transformation from Vedic to Itihasa-Puranic mythology. In the Rigveda, Daksha is an aditya and is associated with priestly skills.

In the epics and Puranic scriptures, he is a son of the creator-god Brahma and one of the Prajapati, the agents of creation, as well as a divine king-rishi. He is the father of many children, who became the progenitors of various creatures. According to one legend, a resentful Daksha conducted a yajna (fire-sacrifice), and deliberately did not invite his youngest daughter Sati and her husband Shiva. In the Linga Purana, for insulting Shiva during this event, which caused Sati to self-immolate in fury, he was beheaded by Virabhadra, a fearsome form of Shiva. He was later resurrected with the head of a goat. Many Puranas state that Daksha was reborn to Prachetas in another Manvantara (age of Manu).
