As per Sthalapurana, Garuda performed Tapas to have the Darshan of Nrisimha of Vibhavathara. Granting the boon to Garuda, the Lord settled amidst the hills and dense forests in nine different forms mentioned above. Hence this holy hill is called Garudadri, Garudachalam and Garudasailam. It is also believed that the Lord killed Hiranyakasipu and saved Prahlada at this Kshetra. As Lord settled here forgetting even the Srivakunta, Mahalakshmi took avatar in the Hunter's family and married the Lord and hence called Senjulakshmi (Senju - Hunterfolk). There is temple for Prahladavarda at lower Ahobilam.
