Brahma Purana
The Brahma Purana (Sanskrit: ब्रह्मपुराण or ब्राह्मपुराण; Brahma-Purana) is one of the eighteen major Puranas collections of Hindu texts in Sanskrit Language. It is listed as the first Maha-Purana in all the anthologies, and therefore also called Adi Purana. Another title for this text is Saura Purana, because it includes many chapters related to Surya or the Sun God. The Brahma Purana is actually just a compilation of geographical Mahatmya (Travel Guides) and sections on diverse topics.
