Gurudwara Sunaartoli Sahib is situated in Distt City Patna near Gurudwara Harmandir Sahib , Patna . Guru Nanak Dev reached Patna and sat at place where Guru Gau Ghat is situated. Guru Nanak Dev ji gave Bhai Mardana Ji a precious stone. Bhai Mardana Ji went to City to sell it. He reached Sunaar toli market. No one rated it right. A Sunaar Murli Dhar took Bhai Mardana Ji to Salas Rai Johri. Salas Rai got amazed to see the stone that he bowed and presented 100 rs as darshan Bheta. Bhai Mardana Ji gave that money to Guru Nanak Dev ji. But Guru Nanak Dev ji returned money as they have not sold the stone yet. Later Salas Rai visited Guru Nanak Dev ji. Guru Nanak Dev ji preached him that he should also evaluate the value of life as he had evaluated the value of stone. Salas Rai became Guru Nanak Dev ji's disciple. On there request Guru Nanak Dev ji came here in Sunar toli market. Guru Nanak Dev ji also visited Salas Rai Johri's house, Where later Guru Gobind Singh took birth.
