Trailokya (Sanskrit: त्रैलोक्य; Kannada: ತ್ರೈಲೋಕ್ಯ; Pali: tiloka, Tibetan: khams gsum; Chinese: 三界; Vietnamese: Tam Giới) literally means "three worlds".[1][2][3] It can also refer to "three spheres,"[3] "three planes of existence,"[4] and "three realms".[4]

^ abBerzin (2008) renders khams-gsum (Wylie; Tibetan) and tridhatu (Sanskrit) as "three planes of existence" and states that it is "[s]ometimes called 'the three realms.'" Tridhatu is a synonym of triloka where dhatu may be rendered as "dimension" or "realm" and loka as "world" or even "planet."
