The enormous diversity of mythology poses a unique challenge to the task of clear presentation, even for those studying the history of stories. The amount of data accessible for modern mythology is immense; every region of India's huge territory has a wealth of its own mythology and traditions, making it impossible to provide a detailed account for this time period. The older eras are similarly considered, albeit with somewhat less force: the Veda, the epics, the Puranas, the Buddhist and Jains' writings, and so on, all present facts in copious amounts. Therefore, it has been necessary to severely limit the subject's scope by limiting the treatment to that mythology that has a close relationship to religion and that gives us an idea of how the Indian imagined the gods and evil spirits who either threatened or supported his existence, as well as the origin of the world and life, the fate of the universe and human souls, and these concepts.
