Starting from Ayodhya, they went right up to Rameshwaram.They found more than 189 ( 60 identified later on) places, most of which still have the memorials connected to the events relating to the life of Shri Ram and Sita and also match the description given in Ramayan (see Map).2 to 7 of map 1) and reached on the banks of Saryu river.After crossing the boundary of Kosal Desh, they entered Shringaverapura (Srigraur) which was kingdom of Nishadraj Guh and is famous for Kewat taking them across Ganga in his boat (20 km from Allahabad).The beginning of the Holocene (post last ice age) is now universally accepted to be around 12000 BP.Consequently the civilizations of the world naturally and simultaneously started developing near the rivers which initially started flowing due to the melting of glaciers near the Equator e.g. When populations multiplied, these river waters became insufficient.In Sunder Kaand there is a reference to lunar eclipse when Hanuman spots Sita in Ashok Vatika (5/19/14, 5/29/7, 5/35/87).
Software shows a solar eclipse on 3rd April 5076 BC which was the only solar eclipse during the entire year.Therefore some people started travelling from south to north.Such northward migration continued for several centuries and finally when these people from south India reached the banks of Himalayan Rivers, they got climatic conditions conducive to long term development of civilization on the banks of these rivers providing security of water, food and shelter for a very long time.Once the astronomical dating was determined around 7000 BP, it appeared that almost all research reports were corroborating such conclusions and opening before us the pages of our true history; shifting many events from the domain of mythology to the realm of realty. This is exactly the time and date when Ramnavmi is celebrated all over India till date (Fig.1). 1: In Valmiki Ramayan it is mentioned in Ayodhya Kaand (2/4/18) that Dashratha wanted to make Shri Ram the king because Sun, Mars and Rahu had surrounded his nakshatra and normally under such planetary positions the king dies or becomes a victim of conspiracies.The story of Shri Ram‘s life was first narrated by Maharishi Valmiki in the ‘Ramayan’ which was written after Shri Ram was crowned as the king of Ayodhya, Maharishi Valmiki had a great sense of astronomy as he has made sequential astronomical references on important dates related to the life of Shri Ram indicating the location of planets vis-à-vis the zodiac constellations and other visible stars (nakshatras). Zodiac sign of king Dashratha was Pisces and his nakshatra was Rewati.
