Gograhana Parva is the forty seventh upa parva included in the fourth Maha parva, namely the Virata parva in Mahabharata. Vyshampayana had narrated the historic events to Janamejaya on his queries.
What had been reported by the servants of Duryodhana after searching for the whereabouts of Pandavas?
Duryodhana was very curious about the whereabouts of Pandava brothers and had sent his secret investigators to all directions. The servants had searched for ten months but could not find any signs of Pandavas anywhere on the Earth. When about eleven months had elapsed, some of the servants had returned. They reported regarding the death of Kichaka and his brothers, killed by unknown Gandharvas overnight. Kichaka was the enemy of Trigartha king, Susharma. Duryodhana was happy to hear the news since the Trigartha king Susharma was his friend.
What had Duryodhana ordered on receiving the suggestions from Karna?
Duryodhana was interested to find the Pandavas during their Ajnathavasa. As per the terms and conditions, Pandavas had to go to forest again for twelve more years if their identity were recognized. Hence Karna and Dushasana suggested sending the servants to all sides once again. Then Duryodhana tried to seek opinions of other seniors.
