Garudachalam / Garudadri
Sri Maha Vishnu manifests himself on the earth in every yuga to punish the wicked and save the virtuous.
A demon named Hiranyaksha started torturing people of different worlds in different ways.
Unable to bear his cruelty, the saints pleaded to Lord Sri Hari for rescue. Demon rolled the entire earth like a mat and took it to the underworld. Goddess Bhudevi prayed Lord of Vaikunta.
Sri Maha Vishnu assumed the form of Shwetha Varaha Swamy killed the demon with his sharp tusks and retrieved the earth on his tusks.
As per the request from saints, angels, kinneras, gandharvas, and yogis, Adi Varaha Swamy stayed back and blessed people from then.
Adivaraha Swamy ordered Garuthmantha as, āOh Garuthumantha! Go back to Sri Vaikuntham and get the kreedadrill hill.ā Immediately Garuda said, Yes and did as commanded.
At the instance of Garuda, it came to be known as Garudadri.
