Autobiograpy Of Gnani Purush A.M.Patel
It was around six, one evening in June 1958, a well dressed gentleman with a black topi(hat)was sitting on a bench on platform number three of Surat railway station in Gujarat. The platform was bustling with people and trains on other lines. He had just finished supper before sunset and was waiting for another train to take him to Vadodara. His name was Ambalal Muljibhai Patel. His assistant stepped away to clean the tiffin. This is when nature unfolded a phenomenal spiritual world within Ambalal. At the end of this spontaneous internal enlightenment, which took about forty-eight minutes, Ambalal came to be known to the world as Gnani Purush Dadashri (master of spiritual science).
