In Indian religions, Patala (Sanskrit: पाताल, IAST: pātāla, lit. that which is below the feet), denotes the subterranean realms of the universe – which are located under the earthly dimension.[1][2][3] Patala is often translated as underworld or netherworld. Patala is described as more beautiful than Svarga (subtle dimensions, loosely translated as heaven). Patala is described as filled with splendid jewels, beautiful groves and lakes.
In Vajrayana Buddhism, caves inhabited by asuras are entrances to Patala; these asuras, particularly female asuras, are often "tamed" (converted to Buddhism) as dharmapala or dakinis by famous Buddhist figures such as Padmasambhava.[4]
In Hindu cosmology, the universe is divided into the three worlds: Svarga, Bhumi or Martya (earth/mortal plane) and Patala (gross dimensions, the underworld).[5] Patala is composed of seven realms/dimensions or lokas,[6][7] the seventh and lowest of them is also called Patala or Naga-loka, the region of the Nagas. The Danavas (children of Danu), Daityas (children of Diti), Rakshas and the snake-people Nagas (serpent-human formed sons of Kadru), live in the realms of Patala.[1]
