The Rama Sethu , Adams Bridge in India was called by the Lankans as ‘Aadhaam Bridge’ because their first Islamic leader traveled over this bridge by foot from India and thus this bridge has a holy connotation for them.
But westerners saw the affinity of the Name to Adam and renamed it as Adams Bridge.
But the name given by Rama to this Bridge is Nala Bridge.
Nala was a vanara of Sugreeva’s army and he was the one who designed it.
(I recall Kaunanidhi asking whether Rama was an Engineer, where he took His degree and was He an Engineer?
Yellow Shawl !
This is the answer.)
“The Ramayana narrates that Sita – the wife of Rama, prince of Ayodhya and avatar of the god Vishnu- was kidnapped by Ravana, the rakshasa (demon) king of Lanka. Rama aided by an army of vanaras (monkeys) reached the end of land and wanted to cross over to Lanka. Rama worships the god of the ocean, Varuna and requests him to make way. When Varuna does not appear before Rama, Rama starts shooting various weapons at the sea, which starts drying up. A terrified Varuna pleads to Rama. Though he refuses to give way, he gives Rama a solution. He tells Rama that Nala, the son of Vishwakarma – the architect of the gods, is amongst his vanara army; Nala has the necessary expertise of an architect, owing to a boon from his divine father. Varuna suggests that Rama construct a bridge across the ocean to Lanka, under the supervision of Nala. Nala volunteers for the task and also comments that the arrogance of the Ocean (Varuna) was tamed by Rama with a threat when love had failed. The vanaras fell mighty trees, and collect logs of wood and giant boulders and cast them in the sea. With the help of the vanara army, Nala completes the 80 miles (130 km) (tenyojana) bridge in just five days. Rama and his army pass over it and reach Lanka, where they prepare to fight Ravana..
Commentaries on the Ramayana elaborate the event. Nala is said to have been born when Vishwakarma embraced Nala’s vanara mother and has an ejaculation. While some commentaries say that other monkeys merely collect the building material, Nala is the one who constructs the bridge; others says that the monkeys build the bridge under his directions.The Kamba Ramayana also solely credits Nala as the architect and builder of the bridge, the Ramacharitamanasa credits Nala and his brother Nila for the creation.
In some versions, Nala is said to have the power to make stones float and, thus, easily makes the sea-bridge. In other versions, another vanara called Nila is also said to have this power and both Nala and Nila are described as builders of the bridge. The tale justifying this power states that in their youth, these monkeys were very mischievous and used to throw the murtis (holy images) worshipped by the sages in the water. As a remedy, the sages decreed that any stone thrown by them in water will not drown, thus saving the murtis. Another tale narrates as assured by Varuna, the stones dropped by Nala and Nila float, but they drift in the sea and do not form a continuous structure, Hanuman, Rama’s devotee and monkey lieutenant suggests that the name of Rama be written, so they stick together; the remedy worked.
