Beneath Mahatala is the planeary system known as Rasatala, which is the abode of the demoniac sons of Diti and Danu. They are called Panis, Nivata-kavacas, Kaleyas and Hiranya-puravasis (those living in Hiranya-pura). They are all enemies of the demigods, and they reside in holes like snakes. From birth they are extremely powerful and cruel, and although they are proud of their strength, they are always defeated by the Sudarsana cakra of the Supreme Personality of Godhead, who rules all the planeary systems. When a female messenger from Indra named Sarama chants a particular curse, the serpentine demons of Mahatala become very afraid of Indra.
