Vishnu – the Hindu god who fights injustice and destroys evil in his various avatars to preserve dharma, has made him an iconic symbol of king's duty and power, an insignia of royalty or dharma. His eagle-like form is shown either alone or with Vishnu, signifying divine approval of the power of the state. He is found on the faces of many early Hindu kingdom coins with this symbolism, either as a single-headed bird or a three-headed bird that watches all sides.

The Garudas have kings and cities, and at least some of them have the magical power of changing into human form when they wish to have dealings with people. On some occasions Garuda kings have had romances with human women in this form. Their dwellings are in groves of the simbalī, or silk-cotton tree. Jataka stories describe them to be residents of Nagadipa or Seruma. The Garuda are enemies to the nāga, a race of intelligent serpent- or dragon-like beings, whom they hunt. The Garudas at one time caught the nāgas by seizing them by their heads; but the nāgas learned that by
