The story of Sanjeevni Booti is an important part of the Ramayana. During the epic war between Lord Rama and Ravana, Lakshmana, the younger brother of Lord Rama, was severely injured by an arrow. The royal physician, Sushena, suggested that the only way to save Lakshmana was to bring the Sanjeevni Booti, a powerful life-restoring herb, from the Dronagiri mountain in the Himalayas. Hanuman, the devoted follower of Lord Rama, took the responsibility to bring the herb. However, when he reached the mountain, he was unable to identify the herb among the many others. In his confusion, he lifted the entire mountain and brought it back to the battlefield. Sushena then identified and used the Sanjeevni Booti to heal Lakshmana. This story symbolizes Hanuman's devotion and strength, and the miraculous powers of the Sanjeevni Booti.

There is no scientific evidence to prove the existence of the Sanjeevni Booti as described in the Ramayana. However, many believe that the herb does exist and is known by different names in different parts of India. As for the Dronagiri mountain, it does exist in the Himalayas in Uttarakhand, India. Many devotees and explorers have tried to find the Sanjeevni Booti there, but none have been successful so far. The story of Hanuman lifting the mountain is depicted in many temples and artworks across India, serving as a cultural evidence of the tale.
