Origin of Vamana Purana
It is held that this Purana has not come down to us in its original form. This is because the five themes of the Puranas i.e. Creation, etc., are scarcely mentioned, and the information given in the Matsya Purana as to the contents and length of the work does not tally with the text.

Apart from this the Vamana Purana also deals with its ten characteristic features. A detailed description of these characteristics will lead one to understand the key note of the Vamana Purana. The characteristics of the Vamana Purana are Sarg, Visarg, Sthan, Poshan, Uti, Vritti, Raksha, Manvantara, Vansh, and Upaashraya.
The origin of the Universe is described in Sarg. Visarg informs about the transformation of a living thing from one species to another. Various means which a man employs for his survival is recorded in Sthan, Poshan, Uti and Vritti. Raksha on the other hand tells about the various incarnation of Lord Vishnu, which he uses for the protection of mankind. Manvantara contains history of the whole Manvantara period. Vansh enlightens us about the pedigree of all kings including Lord Brahma. Upaashraya teaches the real meaning of the word "Brahma".
Thus the Vamana Purana describes the origin of Cosmos, inhabitants of the universe, with the eulogy of both Shiva and Vishnu and a detailed description of the Vamana, the incarnation of Lord Vishnu.
