Buddhist cosmology is the description of the shape and evolution of the Universe according to Buddhist scriptures and commentaries.

It consists of a temporal and a spatial cosmology. The temporal cosmology describes the timespan of the creation and dissolvement of alternate universes in different aeons. The spatial cosmology consists of a vertical cosmology, the various planes of beings, into which beings are reborn due to their merits and development; and a horizontal cosmology, the distribution of these world-systems into an infinite sheet of existential dimensions included in the cycle of samsara. The entire universe is said to be made up of five basic elements of Earth, Water, Fire, Air and Space. Buddhist cosmology is also intwined with the belief of Karma. As a result, some ages are filled with prosperity and peace due to common goodness, whereas other eras are filled with suffering, dishonesty and short lifespans.
