In Hinduism, cosmology refers to the ideas Hindus have about the universe and how it works. Hindus trust that there is a difference between the spiritual and material worlds. Hindu beliefs about the universe are shown through an important text called the Rig Veda. Hindu mythology defines fourteen worlds: seven higher worlds (heavens) and seven lower ones (underworlds). The advanced worlds are the seven, namely Bhu, Bhuvas, Svar, Mahas, Janas, Tapas, and Satya; the lower ones (paatalas) are Atala, Vitala, Sutala, Rasaataala, Talatala, Mahaatala, and Paatala.
Usually, Brahma is the creator, from whom the universe and the four Vedas emerge. The conception of time as almost endlessly repeating itself in kalpas detracts, however, from the uniqueness of the first formation, and Brahma becomes little more than a demiurge.
