Ravana, leading a colossal army, attacked Alakapuri, which was ruled by his older half-brother, Kubera. A fierce battle erupted between the demons and the demigods. Ultimately, the demons emerged victorious. Ravana then seized Kubera's flying chariot, the Pushpaka Vimana, and began traveling to Lanka.
While flying near Mount Kailash, Nandi, the bull-god, commanded Ravana to leave, stating that the mountain was the abode of his master, Lord Shivashankara. Arrogantly, Ravana declared himself the king of all three worlds and claimed not to know anyone named Shivashankara. To display his might, he attempted to uproot Mount Kailash. Ravana began to shake the mountain, but Lord Shiva pushed it back into place with his toe, trapping Ravana beneath it.
Desperate for release, Ravana sang praises to Lord Shiva, which later became known as the Shiva Tandava Stotra. Impressed by his devotion, Lord Shiva forgave Ravana, freed him from the mountain, and presented him with an indestructible sword called the Chandrahasa.
Ravana cried out in pain while trapped under Mount Kailash. This is how he got the name Ravana, which means "one who screams." His former name was Dashagriva (ten-necked).
After Bharata and the others returned to Ayodhya, Rama, Sita, and Lakshmana visited the ashram of Sage Atri. The sage warmly welcomed them and introduced them to his wife, Anasuya.
Anasuya was renowned for her virtues and devotion to her husband. There is a story about a severe ten-year famine that caused a devastating drought on earth. Anasuya, using divine powers obtained through her unwavering faithfulness to her husband, miraculously made the river Ganga flow in the drought-stricken areas. She was also known for her ability to remove obstacles from sages' meditation.
