In fact, the Buddhist heaven has many levels. The "heavenly realm" --just one of the six destinies of transmigration, but often mistaken for heaven--is itself divided into three realms: desire, form and formlessness, which are in turn divided into 28 heavens. The closest realm to humans is the desire realm.
