In Hinduism, the swan (Hamsa) is the vehicle (vahana) of Goddess Saraswati, the deity of knowledge, music, arts, wisdom, and learning. The swan symbolizes purity, discrimination, and spiritual liberation. Just as a swan can separate milk from water, Saraswati helps devotees distinguish between right and wrong, truth and illusion. The presence of the swan signifies the pursuit of knowledge and the transcendence of earthly attachments.
