tri-loka

In Hinduism, loka refers to the universe or a division of it. The most common concept is the tri-loka, or three worlds: heaven, earth, and atmosphere, which later evolved to mean heaven, world, and netherworld. Each of these can be further divided into seven regions, and sometimes a total of 14 worlds are described (seven above and seven below earth). These divisions represent the Hindu idea of numerous, ordered worlds, often associated with specific deities. The brahma-loka is a part of this layered universe, specifically the realm of pious celestial spirits, consisting of multiple heavens where gods reside. Rebirth into these realms is seen as a reward for virtue and meditation, though all lokas are subject to change and recreation. The ultimate goal in Hinduism is moksha, liberation from the cycle of rebirth (samsara) driven by karma, to achieve union with the ultimate reality, brahman.123
