Ramanuja Acarya could understand that, that hunter and his wife were Lakshmi and Narayana. He got that realization from within his heart. When he was lost, in a helpless condition in the forest, he prayed that the shelter of Lord Narayana always protects his devotees. So, on the basis of that humble prayer, Lord Narayana personally came with Lakshmi to bring him back to his home. Then he just sat by the wall weeping and crying in ecstasy thinking of the great mercy that he had just received from the Lord. And then he went back to his home, his mother was very happy to see him. She was thinking it would be at least 6 months but he had returned only after about a month and he told her the story, why he returned early, how Yadava Prakash was planning to kill him. So, she was simultaneously very sad to hear this but very happy that Lord Narayana saved her son.
