This is how Lord Ram found the place to build the bridge
After the abduction of Mother Sita in Panchavati (Nashik), Lord Shri Ram reached Rishyamook Mountain via Sarvatirtha (killing place of Jatayu), Parnashala, Tungabhadra, Shabari Matang Rishi Ashram, crossing Malay Mountains and sandalwood forests. Here he met Hanuman and Sugriva, saw Sita’s jewelery and Shri Ram killed Bali.
Rishyamuk mountain was situated near Kishkindha, the capital of the monkeys mentioned in Valmiki Ramayana. Rishyamook mountain and Kishkindha town are located in Hampi, Bellary district of Karnataka. The nearby hill is considered as ‘Matang Parvat’. On this mountain there was the ashram of Matang Rishi who was the guru of Hanumanji.
After meeting Hanuman and Sugriva here, Lord Shri Ram formed the monkey army and headed towards Lanka. Tamil Nadu has a long coastline, which extends for about 1,000 km. Kodikarai beach is located south of Velankani, bounded by the Bay of Bengal in the east and the Palk Strait in the south. Here Shri Ram’s army camped and Shri Ram gathered his army at Kodikarai and discussed. But after surveying the place, Rama’s army found out that the sea could not be crossed from here and this place was not suitable for building a bridge, then Rama’s army marched towards Rameshwaram.
Rameshwaram beach is a tranquil beach and the shallow water is ideal for swimming and sunbathing. Rameshwaram is a famous Hindu pilgrimage centre. According to the epic Ramayana, Lord Shri Ram worshiped Lord Shiva here before attacking Lanka. The Shivalinga of Rameshwaram is the Shivalinga established by Shri Ram.
According to Valmiki, after three days of searching, Shri Ram found a place in the sea ahead of Rameshwaram from where one could easily reach Sri Lanka. He decided to rebuild from the said place to Lanka with the help of Nala and Neel. Dhanushkodi is a village located on the southern shore of Rameshwaram Island on the east coast of the Indian state of Tamil Nadu. Dhanushkodi is situated to the south-east of Pamban. Dhanushkodi is about 18 miles west of Talaimannar in Sri Lanka
It is named Dhanushkodi because the shape of the bridge (Ram Sethu) built by Nala and Neel through the monkey army from here to Sri Lanka is similar to that of a bow. These entire areas are considered under the Mannar Maritime Region. Dhanushkodi is the only land border between India and Sri Lanka, which is as deep as the sea with some land visible.
Jai Jai Shri Ram
