Aakash se Paataal tak

As per Hinduism it is believe that the entire universe is divided into different divisions. These divisions are known as “Loka”. Each loka is abode for different kinds of species. It is believe that the upper world are of 7 in numbers
1)Bhu-loka, the earth. –It is a division of universe where we live.
2)Bhuvar-loka, the space between the earth and the sun, the region of the Munis, Siddhas, demi-gods like yakshas, kinneras, kimpurushaas,gandharvaas live.
3)Swarg-loka, the abode of Indra, between the sun and the Dhruv Tara(polar star).
4) Mahar-loka, the usual abode of saints, who are supposed to be co-existent with Brahma.
5) Jana-loka, here the 7 manas putras of lord Brahma lives. They were Atri, Vasistha, Angirasa, Marichi, Bhrigu,Daksha, pulasthya.
6) Tapa-loka, where the deities called Vairagis reside. Here the Four first sons of brahma live. They were Sanata, Sanatana, Sanaka,Sananda
The tapaloka,janaloka and maharloka are collectively called MUNILOKA.
7) Satya-loka or Brahma-loka, is the abode of lord Brahma. It is a land of infinity where Lord Brahma and godess Saraswati live here. There is no concept of time in this loka. anddimension. Only infinity exist. Once the soul moves in this world then it will exempt from the trap of birth and rebirth.
The first three worlds are destroyed at the end of each kalpa(one day of Brahma); the last three at the end of his life(hundred of his years); the fourth loka is equally permanent, but is uninhabitable from heat at the time the first three are burning.
