Urdhva lokas

The three highest lokas (realms), Jana, Tapa, and Satya are styled as durable, while Maharloka, has a mixed character; for although it is deserted at the end of the kalpa (aeon), it was not destroyed yet.

[2] The region, where the siddhas and other celestial beings move, is the Earth's atmospheric sphere which also contains space which has its neighbouring planets in the Solar System along with stars and comets.

[4] Above Dhruva, at the distance of ten million leagues, lies the sphere of saints, or Maharloka, the inhabitants of which dwell in it throughout a kalpa, or day of Brahma.

[6] At four times the distance, between the two last, lies the Tapaloka (the sphere of penance), inhabited by the immortal beings and deities called Vaibhrájas, who are highly knowledgeable, pure, and enlightened, whereby they can easily travel to the uppermost realm, Satyaloka, are unconsumable by fire of destruction during the dissolution of the universe.

It is six times the distance (or twelve crores, a hundred and twenty millions of leagues) and is referred to as the sphere of truth, where all the knowledge is available and the inhabitants never die, become old, become ill, have pain and anxiety.
