Swan symbolizes knowledge and self realization.
A famous shloka on Hamsa talks about the symbolism and significance of this majestic bird.
'Oh! Hamsa! Being the auspicious vehicle of Goddess Saraswathi, you carry learning and art upon your shoulders. Give us that discriminating wisdom for which you are famous, such as your proverbial ability to separate the substance of milk from water.'Swan can glide on water without getting its feathers wet. With the help of Brahman knowledge (the knowledge all animate and inanimate is the Supreme Truth - there is only God) we can live in the materialistic world without accumulating dusts of materialism.
Swan can also soar up into the sky from the water body. This symbolizes the need to easily rise above earthly ties. A true yogi needs to perfect these two qualities.
But the greatest quality of Swan is its capacity to separate milk from water. With Brahman knowledge, a person is capable of adapting this quality of Swan and it will help him to swim across the ocean of 'Samsara.' This quality symbolizes the power of discrimination.
The white color of the swan is also the symbol of excellence. In Hindu mythology, the white colored Hamsa, the vehicle of Goddess Saraswathi, lives in the Manasarovar Lake near the Kailash Mountain. In Hindu tradition, the bird is mute and its diet consists of pearls.
Why is this royal swan her vehicle? The answer lies in the special qualities of the swan.
-
The Ability to Discriminate Between 'Water and Milk' (Nir-Ksheer Vichar): The swan is most famous for its ability to separate water from milk. It can drink only the milk, leaving the water behind! This ability makes the swan a symbol of knowledge.
-
Rejection of the Unreal, Acceptance of the Real: The swan's ability to separate water from milk symbolizes the deep philosophical understanding of life. It teaches what is worth accepting and what is worth rejecting. The swan symbolizes the ability to choose knowledge over ignorance, good over evil. It represents the act of rejecting all that is futile, illusionary, or false, and embracing only the essence of truth or real knowledge.
-
Purity and Sacredness: The swan's color is pure white, symbolizing purity and sanctity, and so is the goddess herself, often described as "Sarvashukla" (the one with a pure white form). The swan's white color signifies purity and wisdom, which is why it is a natural companion for Goddess Saraswati, who embodies knowledge and is free of all flaws. This suggests the purity and transcendence of knowledge and spirituality.
-
Focus and Discipline: Achieving knowledge requires focus and discipline—two qualities embodied by the swan. In Hindu philosophy, the swan is also seen as a symbol of discipline and excellence. For a student or seeker of knowledge, these two qualities are essential. The swan, as Saraswati's vehicle, reminds us of the importance of these virtues in our quest for wisdom.
-
Ability to Move Across Three Realms: The swan is capable of moving through water, land, and sky. This tripartite mobility signifies the three realms or dimensions of knowledge. Similarly, as the goddess of knowledge, Saraswati is said to embody knowledge across all domains of existence and creation. Thus, the swan, capable of moving across all three realms, is the perfect vehicle for her.
-
The Concept of 'Hamsa' and 'Paramahamsa': The term "Hamsa" carries deep spiritual significance in Indian philosophy. "Paramahamsa" is a title that denotes the highest level of spiritual enlightenment. In Sanskrit, "Hamsa" is associated with the soul or the Supreme Soul (Paramatma). A person who attains the ultimate spiritual knowledge and reaches the highest state of enlightenment is called a "Paramahamsa." Saraswati's vehicle, the swan, symbolizes this pursuit of ultimate wisdom.
-
Transcendence Over Desire and Knowledge: According to mythology, Saraswati is also considered the consort of Brahma, the creator god. The swan, in many texts, is described as Brahma's vehicle. One interpretation suggests that Saraswati chose the swan as her vehicle to help dissolve Brahma's arrogance. Another view is that when Saraswati's powers (as the goddess of knowledge) are activated in the process of creation, the swan carries knowledge across realms. This relationship signifies the link between divine knowledge and the transcendence of worldly desires.
-
The Transience of Life and Knowledge: The swan is also a symbol of moksha (spiritual liberation). It represents the path to liberation from the cycle of birth and death. The swan’s ability to leave behind the fleeting and the transient symbolizes the quest for eternal truth and knowledge. It suggests that we should renounce all that is temporary and illusory, and seek the eternal knowledge that leads to spiritual freedom.
For all these reasons, it is believed that Goddess Saraswati has chosen the royal swan as her vehicle. The swan represents the wisdom to discern truth, the purity of knowledge, the focus and discipline required for learning, and the ultimate spiritual liberation.
