Trailokya

Trailokya (Skt., त्रैलोक्य trailokya; Pali, tiloka; Standard Tibetan: khams-gsum (Wylie)) has been translated as "three worlds," "three spheres," "three planes of existence," "three realms" and "three regions." These three worlds are identified in Hindu and early Buddhist texts, have counterparts in Brahmanical sources and are elaborated upon by more recent Theosophical theory.
