Vishnu Purana

The Vishnu Purana 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, Pratisarga, Vamsa, Manvantara, and Vamsanucarita. 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.
The Vishnu Purana is among the shorter Purana texts, with about 7,000 verses in extant versions. It primarily centers around the Hindu god Vishnu and his avataras such as Rama and Krishna, but it praises Brahma and Shiva and says that they are dependent on Vishnu. The Purana, states Wilson, is pantheistic and the ideas in it, like other Puranas, are premised on the Vedic beliefs and ideas.
Vishnu Purana, like all major Puranas, attributes its author to be sage Vyasa. The actual author and date of its composition are unknown and contested. Estimates of its composition range from 400 BCE to 900 CE. The text was likely composed and rewritten in layers over a period of time, with roots possibly in ancient 1st-millennium BCE texts that have not survived into the modern era. The Padma Purana categorizes Vishnu Purana as a Sattva Purana.

Date of composition

The composition date of Vishnu Purana is unknown and contested, with estimates widely disagreeing. Some proposed dates for the earliest version of Vishnu Purana by various scholars include:

Horace Hayman Wilson : acknowledged that the tradition believes it to be 1st millennium BCE text and the text has roots in the Vedic literature, but after his analysis suggested that the extant manuscripts may be from the 11th century.
Vincent Smith : 400–300 BCE,
CV Vaidya : ~9th-century,
Moriz Winternitz : possibly early 1st millennium, but states Rocher, he added, "it is no more possible to assign a definite date to the Vishnu Purana than it is for any other Purana".
Rajendra Chandra Hazra : 275–325 CE
Ramachandra Dikshitar : 700–300 BCE,
Roy : after the 9th century.
Wendy Doniger : 450 CE.

Rocher states that the "date of the Vishnu Purana is as contested as that of any other Purana". References to Vishnu ''Purana in texts such as Brihadvishnu whose dates are better established, states Rocher, suggest that a version of Vishnu Purana existed by about 1000 CE, but it is unclear to what extent the extant manuscripts reflect the revisions during the 2nd millennium. Vishnu Purana like all Puranas has a complicated chronology. Dimmitt and van Buitenen state that each of the Puranas including the Vishnu Purana is encyclopedic in style, and it is difficult to ascertain when, where, why and by whom these were written:
Many of the extant manuscripts were written on palm leaf or copied during the British India colonial era, some in the 19th century. The scholarship on Vishnu Purana'', and other Puranas, has suffered from cases of forgeries, states Ludo Rocher, where liberties in the transmission of Puranas were normal and those who copied older manuscripts replaced words or added new content to fit the theory that the colonial scholars were keen on publishing.

Structure

The extant text comprises six amsas and 126 adhyayas. The first part has 22 chapters, the second part consists 16 chapters, the third part comprises 18 chapters and the fourth part has 24 chapters. The fifth and the sixth parts are the longest and the shortest part of the text, comprising 38 and 8 chapters respectively.
The textual tradition claims that the original Vishnu ''Purana had 23,000 verses, but the surviving manuscripts have just a third of these, about 7,000 verses. The text is composed in metric verses or sloka, wherein each verse has exactly 32 syllables, of which 16 syllables in the verse may be free style per ancient literary standards.
The Vishnu Purana is an exception in that it presents its contents in Vishnu worship-related Pancalaksana format – Sarga, Pratisarga, Vamsa, Manvantara, and Vamsanucaritam. This is rare, state Dimmitt and van Buitenen, because just 2% of the known Puranic literature corpus is about these five Pancalaksana'' items, and about 98% is about diverse range of encyclopedic topics.

Vishnu Purana opens as a conversation between sage Maitreya and his Guru, Parashara, with the sage asking, "What Is The Nature Of This Universe And Everything That Is In It?"

First Amsa: Cosmology

The first Amsha of Vishnu Purana presents cosmology, dealing with the creation, maintenance and destruction of the universe. The mythology, states Rocher, is woven with the evolutionary theories of Samkhya school of Hindu philosophy.
The Hindu god Vishnu is presented as the central element of this text's cosmology, unlike some other Puranas where Shiva or Brahma or the Tridevi are offered prominence. The reverence and the worship of Vishnu is described in 22 chapters of the first part as the means for liberation, along with the profuse use of the synonymous names of Vishnu such as Hari, Janardana, Madhava, Achyuta, Hrishikesha and others. The chapters 1.16 through 1.20 of the Vishnu Purana presents the legend of compassionate and Vishnu devotee Prahlada and his persecution by his demon king father Hiranyakashipu, wherein Prahlada is ultimately saved by Vishnu when Vishnu as Narasimha disimbowels and kills Hiranyakashipu. This story is also found in other Puranas.
Vishnu is described in the first book of Vishnu Purana as, translates Wilson, all elements, all matter in the world, the entire universe, all living beings, as well as Atman within every living being, nature, intellect, ego, mind, senses, ignorance, wisdom, the four Vedas, all that is and all that is not.

Second Amsa: Earth

The second part of the text describes the story of earth, the seven continents and seven oceans. It describes Mount Meru, Mount Mandara and other major mountains, as well as Bharatavarsha along with its numerous rivers and diverse people. The seven continents are named Jambu, Plaksha, Salmala, Kusha, Krauncha, Saka, and Pushkara, each surrounded by different types of oceans.
This part of the Vishnu ''Purana describes spheres above the Earth, including the planets, the Sun and the Moon. There are four chapters of the second book that narrate the story of King Bharata, who abdicates his throne to live as a sannyasi. This account is similarly found in sections 5.7 to 5.14 of the Bhagavata Purana. The geography of Mount Mandara is also discussed in this book, and other Puranas. According to Stella Kramrisch, the name may be related to the word mandiram'' and the reason behind its design, image, aim and destination.

Third Amsa: Time

The initial chapters of the third book of the Vishnu Purana presents its theory of Manvantaras,. This is premised upon the Hindu belief that everything is Cyclic, and even Yugas start, complete and then end. Six manvantaras, states the text, have already passed, and the current age belong to the seventh. In each age, asserts the text, the Vedas are arranged into four, it is changed, and this has happened twenty eight times already. Each time, a Vyasa appears and he diligently organizes the eternal knowledge, with the aid of his students.
After presenting the emergence of Vedic schools, the text presents the ethical duties of the four Varnas in chapter 2.8, the four Ashrama of the life of each human being in chapter 2.9, the rites of passage including wedding rituals in chapters 2.10 through 2.12, and Shraddha in chapters 2.13 through 2.16.
The Vishnu Purana asserts that the Brahmana should study the Shastras, worship deities and perform libations on behalf of others, the Kshatriya should maintain arms and protect the earth, the Vaishya should engage in commerce and farming, while the Shudra should subsist by profits of trade, service other varnas and through mechanical labor. The text asserts the ethical duties of all Varnas is to do good to others, never abuse anyone, never engage in calumny or untruth, never covet another person's wife, never steal another's property, never bear ill-will towards anyone, never beat and kill anyone wrongfully. Be diligent in the service of the deities, sages and gurus, asserts the Purana, and seek the welfare of all creatures, one's own children and of one's own soul. Anyone, regardless of their varna or stage of life, who lives a life according to the above duties is the best worshipper of Vishnu and Lakshmi, says the Vishnu Purana. Similar statements on ethical things of people are found in other parts of Vishnu Purana.
The text describes in chapter 2.9, the four stages of life as Brahmacharya, Grihastha, Vanaprastha and Sannyasa. The text repeats the ethical duties in this chapter, translates Wilson. The chapters on Shraddha describe the rites associated with a death in family, the preparation of the dead body, its cremation and the rituals after the cremation.
The third book closes with the Legend Of Vishnu, through Mayamoha, helping the Devas and Devis win over Asuras and Asuris by teaching the Asuras and Asuris heretical doctrines that deny the Vedas, who declare their contempt for the Vedas, which makes them easy to identify and all are killed.
