get the merits of all yagyas and charities or donations just by reading shiva maha puran

 As in puranas - 

By understanding the mysteries of Shivmahapuran and singing its praises, a man attains greater virtues

than that which could be attained by being charitable or by the performance of all the `yagyas'.

Contemplating on the subject matters of Shivmahapuran give auspicious fruits just like a 'Kalpa-taru' (A

mythological tree which fulfills all the wishes).
