Lokāloka literally mean ‘bright and dark’.
The purāṇas like Bhāgavatam describe a mythical mountain called Lokāloka or Cakravāla situated at the southernmost tip of the earth and bordering the sea. It is called Cakravāla since it is circular in shape. It is like hair to mother earth.
Since one side of it is always bright and the opposite side is always dark, it is also called as ‘Lokāloka’. The sun always rises and sets within its circular barrier. The region beyond it is in perpetual darkness. This however is not like an obstacle to the spirits of the virtuous persons, who go to higher worlds.
