Tridhatu

Trailokya (Sanskrit: त्रैलोक्य; Kannada: ತ್ರೈಲೋಕ್ಯ; Pali: tiloka, Tibetan: khams gsum; Chinese: 三界; Vietnamese: Tam Giới) literally means "three worlds". It can also refer to "three spheres," "three planes of existence," and "three realms". Various schemas of three realms (tri-loka) appear in the main Indian religions of Hinduism, Buddhism and Jainism.
