The haṃsa is an aquatic migratory bird, referred to in ancient Sanskrit texts which various scholars have interpreted as being based on the goose, the swan, or even the flamingo. 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 of Brahma, Gayatri, Saraswati, and Vishvakarma.

Brahma is a Hindu god, referred to as "the Creator" within the Trimurti, the trinity of supreme divinity that includes Vishnu and Shiva. He is associated with creation, knowledge, and the Vedas. Brahma is prominently mentioned in creation legends. In some Puranas, he created himself in a golden embryo known as the Hiranyagarbha.
