Buddhist Cosmology
Buddhist cosmology is an intricate and profound framework used to describe the universe's shape, evolution, and realms according to Buddhist scriptures and commentaries. It is not merely a depiction of physical realms but also includes a complex moral and spiritual dimension that is integral to many Buddhist traditions. This cosmology is shared among various branches of Buddhism, including Theravada Buddhism, Mahayana Buddhism, and Tibetan Buddhism.
In Buddhist cosmology, the universe is conceived as a vast system consisting of numerous worlds and realms. Central to this cosmological model is Mount Meru, a sacred mountain often depicted as the center of all physical, metaphysical, and spiritual realms. Surrounding Mount Meru are various planes of existence, including the realms of gods and humans.
Buddhist cosmology traditionally identifies six primary realms of rebirth and existence, which are:
These realms are part of the cycle of samsara, the continuous cycle of birth, life, death, and rebirth that beings undergo.
Buddhist cosmology also includes a temporal aspect, describing the universe's evolution over vast eons of time, known as kalpas. Each kalpa is an immense period during which the universe experiences cycles of formation, existence, dissolution, and void.
Buddhist cosmology also includes various deities and guardians who protect the dharma. Among these are the Four Heavenly Kings, who preside over the four cardinal directions. There are also the Twenty-Four Protective Deities and figures such as Mahabrahma, considered a protector of Buddhist teachings.
