Rasatala or the Under-World

Summary

In Hindu cosmology the universe comprises multiple vertical worlds; beneath the earth lie subterranean realms collectively known as Rasātala or Pātāla. This article investigates the myths, philosophy and early scientific ideas associated with these under‑worlds. Beginning with Purāṇic descriptions, the author recounts how Rasātala is depicted as a region inhabited by nāgas and asuras, replete with palaces adorned with jewels and illuminated by their own light. He then analyses philosophical interpretations that view the “world below” not merely as a physical domain but as a symbolic plane representing unconscious or latent forces. The essay compares Indian conceptions of subterranean worlds with those of ancient Greece and Mesopotamia, highlighting similarities in mythic geography. In its second half the paper surveys references in classical Sanskrit literature to natural phenomena that hint at an awareness of deep time and geological processes: texts of the Vaiśeṣika and Sāṅkhya schools describe atoms (aṇu), the constitution of matter and the cyclic destruction of worlds; the Nyāya tradition proposes a wave‑theory to explain sound. Commentaries on Patañjali’s Mahābhāṣya are cited to show early discussions of gravity and magnetism. The author argues that while these ideas were not part of a systematic science, they reveal that ancient Indian thinkers speculated about the structure of the earth and the existence of regions below the surface. The article concludes that the concept of Rasātala served both a mythological function, providing a rich setting for stories of gods and demons, and a philosophical function, prompting inquiry into the unseen principles governing the universe.
