If one looks at the geography of Hoshangabad, Madhya Pradesh, Maharashtra( which lies in the Deccan plateau right at the center) and Andhra Pradesh, one can find the description by Valmiki about the emergence of Hanuman form the Vindhya range would tally with the geography found now..
Madhya Pradesh to Maharashtra to Andhra, Correct sequence.
Now Swayamprabha transported Hanuman and the Vanara sena through the Vindhya Wormhole.
The apocalyptic laughter of Shiva is referred as Attahasa.
Some scholars are of the view that this a future manifestation of Shiva.
Shiva took the form of Attahasa in a mountain in the Himalayan Range.The sons of Shiva will also reside in the Attahasa mountain range in the 20th yuga.-Vayu Purana.
For example there is a temple in Andhra Pradesh where Hanuman rested while bringing the Sanjivi Parvatha.,Vellala Hanuman Temple, or
Temple in Tamil Nadu where Rama and Hanuman confer in private.
Please read my posts on these.
All these are accounted in the Map provided here.
The information is scarce, despite a lot of information in the web on Rama’s travels through out the country.
There is Rishyasrunga Hill near Sringeri.
5.Rama’s sister was married to Shanta to Romapada.Romapada was the King of Anga Desa, now in Pakistan, near Mohenjo Daro. His son-in-law was Rishyasrunga, which makes Rishyasrunga Rama’s Sister’s husband!
A king named Dasharatha will be born into Ikshwaku dynasty who will be very virtuous, resplendent and truthful one to his vow.” Said Sanat Kumara, the Sage.”King Dasharatha will befriend the king of Anga and the king of Anga will beget a fortunate girl named Shanta.
Shanta is said to be the daughter of Dasharatha and given to Romapada in adoption, and Rishyasringa marries her alone. This is what Sumantra says to Dasharatha at 1-9-19.
Valmiki’s Ramayan contains graphic and poetic details of eight constellations during Hanuman’s return journey from Sri Lanka to Sunaabh Hill in the middle of the sea which apparently took about four and a half hours from 6:30 a.m. to 11 a.m. All these details of planets and nakshtras with reference to eight constellations described in Sarga 57(1,2,3) of chapter 5 tally exactly with the sky view generated by the software for the morning of 14th September 5076 BC.”
