Dunagiri (7,066 m) is one of the high peaks of the Chamoli District Himalayas in the northern Indian state of Uttarakhand. It lies at the northwest corner of the Sanctuary Wall, A ring of peaks surrounding Nanda Devi and enclosing the Nanda Devi Sanctuary. According to Ramayana, Sanjeevani is a magical herb which has the power to cure serious nervous system problems. It was believed that medicines prepared from this herb could revive in any situations where death is almost certain. The herb is mentioned in the Ramayana when Ravana's son Indrajit (Meghnada) hurls a powerful weapon at Lakshmana. Lakshmana is badly wounded and is nearly killed. Hanuman was called upon to fetch this herb from the mount Dronagiri (Mahodaya) or Gandhamardhan hills, far to the north of the Vindhyas on the slopes of the Himalayas. The mountain of herbs is identified as the Valley of Flowers near Badri in Uttarakhand on the slopes of the Himalayas. It is sometimes called Gandhamardan, and at other times Dronagiri. Upon reaching Dronagiri Parvata or Gandhamardan, Hanuman could not identify the herb and lifted the whole mountain and brought it to the battlefield.
