Lifting a Mountain and Why he is called "langra veer"

When Lakshmana is severely wounded during the battle against Ravana, Hanuman is sent to fetch the Sanjivani, a powerful life-restoring herb, from Dronagiri mountain in the Himalayas, to revive him. Ravana realises that if Lakshmana dies, a distraught Rama would probably give up, and so he dispatches the sorcerer Kalanemi to intercept Hanuman.Kalanemi, in the guise of a sage, deceives Hanuman, but Hanuman uncovers his plot with the help of an apsara, whom he rescues from her accursed state as a crocodile.
Ravana, upon learning that Kalanemi has been slain by Hanuman, summons Surya to rise before its appointed time because the physician Sushena had said that Lakshmana would perish if untreated by daybreak. Hanuman realizes the danger, however, and, becoming many times his normal size, detains the Sun God to prevent the break of day. He then resumes his search for the precious herb, but, when he finds himself unable to identify which herb it is, he lifts the entire mountain and delivers it to the battlefield in Lanka. Sushena then identifies and administers the
herb, and Lakshmana is saved. Rama embraces Hanuman, declaring him as dear to him as his own brother. Hanuman releases Surya from his grip, and asks forgiveness, as the Sun was also his Guru.

Hanuman was also called "langra veer"; langra in Hindi means limping and veer means "brave". The story behind Hanuman being called langra is as follows. He was injured when he was crossing the Ayodhya with the mountain in his hands. As he was crossing over Ayodhya, Bharat, Rama's young brother, saw him and assumed that some Rakshasa was taking this mountain to attack Ayodhya. Bharat then shot Hanuman with an arrow, which was engraved with Rama's name. Hanuman did not stop this arrow as it had Rama's name written on it, and it injured his leg. Hanuman landed and explained to Bharat that he was moving the mountain to save his own brother, Lakshmana. Bharat, very sorry, offered to fire an arrow to Lanka, which Hanuman could ride in order to reach his destination more easily. But Hanuman declined the offer, preferring to fly on his own, and he continued his journey with his injured leg.
