"Is Hanuman alive?" asked Jambavan. "If Hanuman is alive, there is no need for panic. He will find a way out of this."
Encouraged by Jambavan's words, Hanuman bowed to him. The monkeys and Vibhishana discussed how to revive Lakshmana. Finally, Vibhishana suggested that the royal physician of Lanka, Sushena, could resuscitate him. Hanuman immediately set out and returned with the demon doctor a short while later. After examining Lakshmana, Sushena declared that he could be saved if someone fetched the Sanjeevani herb ('the herb of immortality') from Mount Dronagiri in the Himalayas before daybreak.
Hanuman embarked on his journey to find the Sanjeevani herb. Meanwhile, Ravana's spies informed him of the monkey army's plan and Hanuman's mission. Determined to create obstacles, Ravana used his demonic powers to hinder Hanuman. On his way to the Himalayas, Hanuman encountered Kalanemi, a formidable demon sent by Ravana. Recognizing Kalanemi's intent to obstruct Lord Rama's mission, Hanuman engaged in battle with the demon. Despite Kalanemi's efforts, he was no match for Hanuman, who ultimately killed him.
Hanuman finally reached Mount Dronagiri, which held the magical herb. According to the demon doctor’s instructions, the herb that sparkled with light was the Sanjeevani. But to Hanuman's astonishment, light sparkled beneath all the herbs on the mountain. Realizing this was due to demonic magic and not wanting to waste precious time searching for the Sanjeevani, Hanuman lifted the entire mountain and carried it toward Lanka!
He reached the unconscious Lakshmana before dawn. The demon physician Sushen carefully picked the Sanjeevani herb from the mountain Hanuman had brought. He extracted its juice and made Lakshmana drink it. Lakshmana slowly revived as if awakening from a deep sleep. Rama was overjoyed and hugged his beloved brother, and waves of happiness spread through the monkey army.
