Buddhist cosmology
A Buddhist mandala from ancient India depicts Mount Meru standing at the center of a terrestrial universe. This immense mountain rises 80,000 yojanas above sea level and extends another 80,000 yojanas below it into layers of golden earth and water. The sun and moon revolve around this central peak while four continents float in an ocean surrounding its base. Jambudvīpa occupies the southern quadrant as the dwelling place for ordinary humans shaped like a blunt-nosed triangle with a point facing southward. A giant Jambu tree stands one hundred yojanas tall within this continent where human lifespans vary between ten years to eighty thousand years depending on moral conduct.
Three other continents surround the world system: Pūrvavideha lies to the east shaped like a semicircle with people living seven hundred years who trade materials daily. Aparagodānīya sits in the west as a circular landmass five hundred years long where inhabitants sleep directly upon the ground without houses or private property. Uttarakuru exists in the north as a square region eight thousand yojanas wide featuring cities built in air and food that grows spontaneously without labor. These four islands remain unreachable by normal sailing vessels though cakravartin kings once used treasure called cakraratna to fly through space connecting them across vast distances.
The vertical structure of Buddhist cosmology divides existence into three realms containing thirty-one distinct planes based on mental states rather than physical location alone. Beings born into these worlds experience different degrees of happiness, suffering, duration, and perception according to their karma from previous lives. The lowest realm known as Kāmadhātu contains fifteen planes including six unhappy states such as hells hungry ghosts animals demons gods and humans bound by sensual desire and Māra's influence.
Above this lies Rūpadhātu comprising eighteen planes inhabited by beings possessing subtle bodies composed of invisible matter visible only to other form-realm dwellers. These devas live within four dhyana levels ranging from first meditation state Brahmā worlds up through fourth dhyana Vehapphala heavens spanning heights measured in millions of yojanas above Earth. Pure Abodes Śuddhāvāsa exist exclusively for Anāgāmins non-returners who attain enlightenment directly there without rebirth elsewhere while remaining inaccessible to Bodhisattvas destined human incarnations.
Highest still exists the Formless Realm Arūpyadhātu consisting merely four planes where inhabitants possess pure consciousness devoid of shape or spatial coordinates yet endure lifespans reaching billions of years. Sphere of Infinite Space spans twenty thousand mahakalpa durations followed by infinite consciousness lasting forty thousand then nothingness sixty-fourth sphere neither perception nor non-perception extending eighty-four thousand kalpas total life span.
Time flows cyclically across great eons called mahākālpa measuring creation duration dissolution emptiness repeated infinitely throughout existence. Each cycle begins with Vivartakalpa evolution moment when primordial wind builds structures destroyed previously allowing beings descending higher realms populate lower forms again.
