Describing how Garuda pleased him with his deep devotion, Lord Vishnu said– ‘During ancient times Garuda once did an austere penance to please me. I appeared before him and expressed my willingness to fulfil anything that he wished for. Garuda wanted to liberate his mother, Vinta from the slavery of Kadru-the mother of serpents. He also wanted to avenge his mother’s humiliation at their hands. He also expressed his desire of becoming immortal by having a Purana credited to his name and finally he requested me to give him the privilege of becoming my mount. I blessed Garuda as the result of which all his wishes were fulfilled. Once, on being requested by sage Kashyap, Garuda narrated the divine tales of Garuda Purana to him. Sage Kashyap had once brought back a dead tree back to life with the help of Garudi Vidya- a sacred mantra found in Garuda Purana. Similarly, Garuda too had brought numerous dead creatures back to life with the help of same mantra.’
