Garuda and the Valakhilyas, Vishnu and Garuda

Garuda saves the Valakhilya Rishis from falling from the tree in which they are doing tapas. They give him the name Garuda, "Bearer of Heavy Weight." After completing his assignment of delivering the Amritam, without partaking himself, Garuda receives from Lord Vishnu the boon of being his Vahana. (Mahabharata)
