Sculpture of Vamana, an avatar of Vishnu, who is associated with the legend of taking three strides upon the three worlds
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]
The concept of three worlds has a number of different interpretations in Hindu cosmology.
Traditionally, the three worlds refer to either the earth (Bhuloka), heaven (Svarga), and hell (Naraka),[5] or the earth (Bhuloka), heaven (Svarga), and the netherworld (Patala)[6]
The Brahmanda Purana conceives them to be Bhūta (past), Bhavya (future), and Bhavat (present)[7]
In Vaishnavism, the three worlds are often described to be bhūr, bhuvaḥ, and svaḥ (the gross region, the subtle region, and the celestial region)[8]
In the Nilanamatapurana, Vamana covers his second step on the three worlds of Maharloka, Janaloka, and Tapoloka, all of which are regarded to be a part of the seven heavens[9]
Kāmaloka the world of desire, typified by base desires, populated by hell beings, preta (hungry ghosts), animals, humans and lower demi-gods.
Rūpaloka is the world of form, predominantly free of baser desires, populated by dhyāna-dwelling gods, possible rebirth destination for those well practiced in dhyāna.
Arūpaloka is the world of formlessness, a noncorporeal realm populated with four heavens, possible rebirth destination for practitioners of the four formlessness stages.[3]

^ 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."
