In another incident during the war, Rama and Lakshmana are captured by the rakshasa Mahiravana (or Ahiravan), brother of Ravana, who held them captive in their palace in Patala (or Patalpuri) --the netherworld. Mahiravana keeps them as offerings to his deity. Searching for them, Hanuman reaches Patala, the gates of which are guarded by a young creature called Makardhwaja (known also as Makar-Dhwaja or Magar Dhwaja), who is part reptile and part Vanara.

The story of Makardhwaja's birth is said to be that when Hanuman extinguished his burning tail in the ocean, a drop of his sweat fell into the waters, eventually becoming Makardhwaja, who perceives Hanuman as his father. When Hanuman introduces himself to Makardhwaja, the latter asks his blessings, but fights him to fulfill the task of guarding the gate. Hanuman defeats and imprisons him to gain entry.

Upon entering Patala, Hanuman discovers that to kill Mahiravana, he must simultaneously extinguish five lamps burning in different directions. Hanuman assumes the Panchamukha or five-faced form of Sri Varaha facing north, Sri Narasimha facing south, Sri Garuda facing west, Sri Hayagriva facing the sky and his own facing the east, and blows out the lamps. Hanuman then rescues Rama and Lakshmana. Afterwards, Rama asks Hanuman to crown Makardhwaja king of Patala. Hanuman then instructs Makardhwaja to rule Patala with justice and wisdom.

To date Chandraloak Devpuri mandir is located at Dugana a small village 17 km from Laharpur,Sitapur district,Uttar Pradesh. A divine place where Chakleswar Mahadev situated.

Mountain Lifting

 

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.[22] 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.[22] 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. thumbnail 

  In the Ramayana Hanuman changes shape several times. For example, while he searches for the kidnapped Sita in Ravana's palaces on Lanka, he contracts himself to the size of a cat, so that he will not be detected by the enemy. Later on, he takes on the size of a mountain, blazing with radiance, to show his true power to Sita.[21] Also he enlarges & immediately afterwards contracts his body to out-wit Sirsa, the she-demon, who blocked his path while crossing the sea to reach Lanka. Again, he turns his body microscopically small to enter Lanka before killing Lankini, the she-demon guarding the gates of Lanka. He achieved this shape-shifting by the powers of two siddhis; Anima and Garima bestowed upon him in his childhood by Sun-God, Surya. 
Finding Sita Hanuman reaches Lanka and marvels at its beauty. After he finds Sita in captivity in a garden, Hanuman reveals his identity to her, reassures her that Rama has been looking for her, and uplifts her spirits. He offers to carry her back to Rama, but she refuses his offer, saying it would be an insult to Rama as his honour is at stake. After meeting Sita, Hanuman begins to wreak havoc, gradually destroying the palaces and properties of Lanka. He kills many rakshasas, including Jambumali and Aksha Kumar. To subdue him, Ravana's son Indrajit uses the Brahmastra. Though immune to the effects of this weapon Hanuman, out of respect to Brahma, allows himself be bound. Deciding to use the opportunity to meet Ravana, and to assess the strength of Ravana's hordes, Hanuman allows the rakshasa warriors to parade him through the streets. He conveys Rama's message of warning and demands the safe return of Sita. He also informs Ravana that Rama would be willing to forgive him if he returns Sita honourably. Enraged, Ravana orders Hanuman's execution, whereupon Ravana's brother Vibhishana intervenes, pointing out that it is against the rules of engagement to kill a messenger. Ravana then orders Hanuman's tail be lit afire. As Ravana's forces attempted to wrap cloth around his tail, Hanuman begins to lengthen it. After frustrating them for a while, he allows it to burn, then escapes from his captors, and with his tail on fire he burns down large parts of Lanka. After extinguishing his flaming tail in the sea, he returns to Rama.  
Meeting with Rama

 

Hanuman meets Rama during the Rama's 14-year exile. With his brother Lakshmana, Rama is searching for his wife Sita who had been abducted by Ravana. Their search brings them to the vicinity of the mountain Rishyamukha, where Sugriva, along with his followers and friends, are in hiding from his older brother Vali. Having seen Rama and Lakshmana, Sugriva sends Hanuman to ascertain their identities. Hanuman approaches the two brothers in the guise of a brahmin. His first words to them are such that Rama says to Lakshmana that none could speak the way the brahmin did unless he or she had mastered the Vedas. He notes that there is no defect in the brahmin's countenance, eyes, forehead, brows, or any limb. He points out to Lakshmana that his accent is captivating, adding that even an enemy with sword drawn would be moved. He praises the disguised Hanuman further, saying that sure success awaited the king whose emissaries were as accomplished as he was. When Rama introduces himself, the brahman identitifies himself as Hanuman and falls prostrate before Rama, who embraces him warmly. Thereafter, Hanuman's life becomes interwoven with that of Rama. Hanuman then brings about friendship and alliance between Rama and Sugriva; Rama helps Sugriva regain his honour and makes him king of Kishkindha. Sugriva and his vanaras, most notably Hanuman, help Rama defeat Raavana and reunite with Sita. In their search for Sita, a group of Vanaras reaches the southern seashore. Upon encountering the vast ocean, every vanara begins to lament his inability to jump across the water. Hanuman too is saddened at the possible failure of his mission, until the other vanaras and the wise bear Jambavantha begin to extol his virtues. Hanuman then recollects his own powers, enlarges his body, and flies across the ocean. On his way, he encounters a mountain that rises from the sea, proclaims that it owed his father a debt, and asks him to rest a while before proceeding. Not wanting to waste any time, Hanuman thanks the mountain and carries on. He then encounters a sea-monster, Surasa, who challenges him to enter her mouth. When Hanuman outwits her, she admits that her challenge was merely a test of his courage. After killing Simhika, a rakshasa, he reaches Lanka.
