The division of lokasSometimes different “planes” or “realms” lokas are posited, which are corresponding “environments” for the different bodies: these are the bhûrloka (earth), bhuvarloka (the subtle planes or atmosphere), svarloka (the heavenly realm), maharloka, janarloka (these first five correspond to the panchakoshas — "five koshas"), and then there are the highest lokas, sometimes known as tapoloka, satyaloka, siddhaloka, and brahmaloka.
Scriptures offer several cosmological perspectives, most importantly sapta urdhvaloka (seven upper worlds) and sapta adholoka (seven lower worlds), which correspond to the 14 chakras and make up the "world-egg of God," the universe, called Brahmanda.
Sapta Urdhvaloka — the seven upper worldsThe seven “upper worlds” are a more detailed breakdown of the “three worlds”. The second, third and fourth comprise the subtle plane. The highest three comprise the causal plane. From the perspective of the seven worlds, the Brahmaloka is of three levels: Janaloka, "creative plane" (vishuddha chakra); Tapoloka, "plane of austerity" (ajna chakra); and Satyaloka, "plane of reality" (sahasrara chakra).
