Shiv Maha Purana contains the essence of Vedantic philosophy, which gives worldly pleasures as well as Salvation. Mere remembrance of it and Shiva, destroys all the sins of a man.

"O revered Sages! The source of Vishnu, Rudra all the deities and all the other creations is none other Mahadev. Union with the Shiva should be the objective of a man to attain that objective. Listening to the qualities of Lord Shiva, singing devotional songs in his praise and contemplating on him are the greatest means, which help to unite with Shiva." ~ Shivmaha Purana. Yes, Listening, Kirtan, Contemplation ~ SHRAVAN, KIRTAN, MANAN, the three main activities mentioned in the Shiv Maha Purana are the supreme means to attain liberation. Purification of the mind by the help of doing worship and chanting the name of God is called contemplation. Singing devotional songs in the form of stotra, or hymns of the vedas or even in one's own language is called Kirtan. ‪The Greatness of ShivaLingam is described in Shiv Purana. If a person is incapable of following Shravan, Kirtan and Manan then he should worship the ShivaLingam. Even by doing this he can attain liberation from all the bondages of the world. It's mentioned in Shiv Maha Puran that in Kaliyuga when all the castes have forgotten about their respective duties, to prevent the deterioration in the human values listening of Shiv Maha Purana and worship of ShivaLingam is the only means by the help of which a man can achieve benediction. Shiv Maha Purana contains the essence of Vedantic philosophy, which gives worldly pleasures as well as Salvation. Mere remembrance of it and Shiva, destroys all the sins of a man.
Love, Light & Peace ~ Shiva Shiva Om Namah Shivaya!
