There is much to learn from the Markandeya Purana. Its reputed author is Veda-Vyasa.
The purana as a type of literature existed in oral form a thousand years before many of them were written down between 300 and 750 CE, and modified throughout centuries into medieval times and further. There are about twenty mahapuranas (great puranas) and over twenty lesser puranas today.
A purana (Sanskrit: "Ancient Lore") belongs to a class of Hindu writings that were written down chiefly between 300 and 750 CE "all over India". The Puranas became the scriptures of the common people and available to everybody, unlike the Vedas, who were restricted to initiated men. The Puranas comprise popular myths and legends and other traditional lore. In addition to such stories there is a wealth of maxims to regulate one's living. Extracts of a large part of the Markandeya Purana are below. - T. K.
MANY PURANAS. Vyasa, the author of the Markandeya Purana according to tradition, and of the Mahabharata poem too, is also known as Krishna-Dvaipayana. The Puranas were intended for people who could not go into high Sanskrit philosophy with its intricacies. Stories from 18 main Puranas and just as many subsidiary Puranas were told in markets and other common places, and intertwined in the stories there are norms and proverbial sayings, and much else.
NOT STRICT CONSISTENCY: Six Puranas glorify Brahma, six Vishnu, and six Shiva. In the Shiva Purana, Shiva is highly eulogised and Vishnu is put in an inferior position and sometimes belittled. In the Vishnu Purana it is the other way round; Hari (Vishnu) is highly eulogised an Shiva is given an inferior position. Redactions and changes over the centuries can explain shifts of focus and modifications like these.
SHAREWARE TALES ABOUND: Not a few ancient stories are shareware among the different Puranas, and further too. For example, a story of the fire-god Agni from the still older Vedas, reappears in the Srimat Bhagavata (about Vishna as Krishna), with Krishna presented as the main character of that story, and so on.
VYASA TALES: According to a long epic poem that Vyasa himself dictated and Hindus revere, Vyasa was born on the same day as his mother conceived, understood life wery well and soon walked away from there, while his mother still looked exactly like a virgin after giving birth to him.
This is made plain in the very first part (parva) of the ancient epic poem Mahabharata. The epic poem was dictated by Vyasa himself, and all his reputed output is a rather large part of Hinduism.
The Markandaya Purana is an old Sanskrit work. It contains a poem that seems to have been composed before the beginning of the 900s at the latest. Various estimates would place it about the 300s CE. (p. xiii, xiv)
Among the deities in it, Indra and Brahma are mentioned the most often, next are Vishnu and Shiva, then the Sun and Agni, who is the Aryan fire god. (p. xv)
The orientalist and translator Frederick Eden Pargiter's (1852-1927) conclusions are that the latest part was complete in the 800s CE and "very probably" in the 400s or 500s CE. The third and fifth parts of the work constituted the original Purana, and they probably existed in the 200s CE, perhaps earlier. The first and second part were composed between the two periods. (p. xx)
In it we read about such variegated topics as the states which are said to lead to final emancipation from existence [shudder]; the course of the Ganges in the sky; a row of renowned forefathers called Manus and their fabled descendants; and the goddess Maha-Maya.

[ ] - hopefully a fairly good quotation (it is a direct quotation of the translation of the Sanskrit scholar Pargiter);
Wealth and virtue, love and soul liberation [freedom, etc.] compose a fourfold unity of Hindu ideals [cf 6].
Artha, dharma (moral responsibility etc.), kama and moksha are the Sanskrit names of life goals that stand out. They are more or less intertwined. For example, wealth and love are said to relate to dharma in such ways that if inherent dharma (righteousness) is violated, the wealth and health and sense or career - and love - wanes in time too, sooner or later, as results of wrong deeds and their resultant moral weakening or abandonment. That is an ancient teaching that stresses the value of morality for sound accomplishments of any lovable kind. "You have to act morally to succeed well sub specie aeternitatis (in a universal perspective)," in other words.

I give you what is infested with vermin, the content of broken pots, what is unripe, what has been licked, polluted, and also damaged food and drink. These are to nourish you, besides what has been given away in anger or pain. You will always conquer among men who have been corrupted.
Your business is to create social dissentions. Men who fast vainly, who always delight in women, and religious hypocrites are for the taking.

Abandon the house where the lotus and the white lotus are found, where a maiden dwells who feeds on sweetmeats and - where a fine bull is kept. And do not roam in the house where the great festivals that were famous of old, are celebrated.
Do not join yourself with the man who establishes the country customs and maintains good life according to the precepts," Brahma finally said. [cf 38-97]
