Vahana (वाहन, or animal vehicle, literally "that which carries, that which pulls") denotes the being, typically an animal or mythical, a particular Hindu God is said to use as a vehicle. In this capacity, the vahana is often called the deity's "mount". Upon the partnership between the deity and his vahana is woven much iconography and Hindu theology. Deities are often depicted riding (or simply mounted upon) the vahana. Other times, the vahana is depicted at the deity's side or symbolically represented as a divine attribute. The vahana may be considered an accoutrement of the deity: though the vahana may act independently, they are still functionally emblematic or even syntagmatic of their "rider". The deity may be seen sitting or standing on the vahana. They may be sitting on a small platform, or riding on a saddle or bareback.
Vah in Sanskrit means to carry, or transport.
In Hindu iconography, positive aspects of the vehicle are often emblematic of the deity that it carries. Nandi the bull, vehicle of Shiva, represents strength and virility. Dinka the mouse, vehicle of Ganesha, represents speed and sharpness. Parvani the peacock, vehicle of Kartikeya, represents splendor and majesty. The hamsa, vehicle of Saraswati, represents wisdom, grace, and beauty.
However, the vehicle animal also symbolizes the evil forces over which the deity dominates. Mounted on Parvani, Kartikeya reins in the peacock's vanity. Seated on Dinka the rat (Mushika), Ganesha crushes useless thoughts, which multiply like rats in the dark. Shani, protector of property, has a vulture, raven, or crow within whom he represses thieving tendencies. Under Shani's influence, the vahana can make even malevolent events bring hope.
Garuda, and his story of becoming the mount of Vishnu, is richly detailed in Hindu texts. Born to Vinata and bearing the power of Kashyapa's penance, the demigod is anguished to find that his mother is enslaved by the cruel Kadru. When he pleaded with Kadru to free his mother, the latter demanded the nectar of immortality as the price of her liberty.
