Guess what this text could be! In fact it could be found from the image itself. Yes, it is Mahabharatha - Mausala Parva, Adhyaaya 8, Sloka 40 (highlighted in red box). Getting what it is? Here is the English translation of this verse:

Niyathi thu Janae thasminsaagaro makaraalaya:Dhwaarakaam ranthasampoornam jalaenaaplaavayaththadhaa

And here is the core meaning of this sloka:
It is indeed the destiny of people to go into water as the city of Dhwaraka will be completely submerged under the ocean.

On May 19, 2001, India's science and technology minister Murli Manohar Joshi announced the finding of ruins in the Gulf of Khambhat. The ruins, known as the Gulf of Khambhat Cultural Complex (GKCC), are located on the seabed of a nine-kilometer stretch off the coast of Gujarat province at a depth of about 40 m. The site was discovered by a team from the National Institute of Ocean Technology (NIOT) in December 2000 and investigated for six months with acoustic techniques. A follow up investigation was conducted by the same institute in November 2001, which included dredging to recover artifacts. A round of further underwater explorations was made in the Gulf of Khambhat site by the NIOT team from 2003 to 2004, and the samples obtained of what was presumed to be pottery were sent to laboratories in Oxford, UK and Hannover, Germany, as well as several institutions within India. And it is proved that the artifacts could be dated back to 2500 BC to 1400 AD. So, it is not that Mahabharatha is just a story. It could tell us a great history of an important part of the world called India if we read it carefully!... THE PATH WILL BE FOLLOWED...
