Buddhism divides the so-called Three Realms and Six Paths. The lowest layer is the Hell Path, followed by the Hungry Ghost Path, the Beast Path, the Human Path, the Asura Path, and the Heavenly Path.
In the Heavenly Path, there are celestial beings, divided into three realms with twenty-eight levels of heaven. In the Desire Realm, there are six levels of heaven. The Four Heavenly Kings reside halfway up Sumeru Mountain, with Duo Wen, Guang Mu, Zeng Zhang, and Chi Guo living in the east, west, south, and north, respectively.
Next is Daoli Heaven, located at the top of Mount Sumeru, where Emperor's Heaven is located.
Any sentient being, transformed by a Buddha or Bodhisattva, can only be ferried to this heaven. Shakyamuni transformed his own mother, and Ksitigarbha Bodhisattva transformed his own mother, only to reach Daoli Heaven. Beyond that, one must cultivate on their own and cannot rely on others to forcibly pull them up.
