The Hansa (Sanskrit: हंस Hansa or hamsa) is an aquatic migratory bird, referred to in ancient Sanskrit texts which various scholars have interpreted as being based on the goose, the swan,[2] or even the flamingo.[1][3] Its image is used in Indian and Southeast Asian culture as a spiritual symbol and a decorative element. It is also used in a metaphorical sense with the bird attributed with the mythical ability to extract milk from a mixture of milk and water or good from evil. In Hindu iconography, hamsa is the vahana (or vehicle) of Brahma, Gayatri, Saraswati, and Vishvakarma.[3]
