"A medieval symbol for the opened third eye was a swan with unfurled wings. The body of the swan represented the pineal gland, and its wings were the two sides of the brain. The complete swan was a symbol of the higher consciousness of the soul. The Knights of the Swan were those who understood these secrets."
"Paramahamsa (परमहंस), also spelled paramahansa or paramhansa, is a Sanskrit religio-theological title of honor applied to Hindu spiritual teachers who are regarded as having attained enlightenment. The title literally means "supreme swan," and symbolizes spiritual discrimination. The swan is equally at home on land and on water; similarly, the true sage is equally at home in the realms of matter and of spirit. To be in divine ecstasy and simultaneously to be actively wakeful is the paramahansa state; the 'royal swan' of the soul floats in the cosmic ocean, beholding both its body and the ocean as manifestations of the same Spirit. The word 'Paramahamsa' means One whos is Awakened in all realms.  Paramahansa is the highest level of spiritual development in which a union with ultimate reality has been attained by a sannyasi."
"The hamsa (swan) is the vahana, the mount or vehicle, of the god Brahma. In the Vedas and the Purânas it is a symbol for the soul/Soul. The hamsa is said to be is the only creature that is capable of separating milk from water once they have been mixed; symbolically this is the display of great spiritual discrimination. It is symbolic for a spiritually advanced being who is capable of controlling the breath energy in such a way that he only absorbs pure vibrations from all the different energies the world contains. To the Paramahamsa (the supreme celestial Swan) on the other hand, the whole of creation is God himself, there is nothing else but God alone. This person is a fully realized soul, completely liberated from all bonds with the world, who knows no obligations, no likes or dislikes. He is without any needs because he is completely immersed in God."
"Paramhansa — Literally — Supreme Swan, a person of the highest spiritual realization. Mythically, a swan can separate milk from water and is therefore an apt symbol for one who has discarded the unreal for the Real, the darkness for the Light, and mortality for the Immortal, having separated himself fully from all that is not God and joined himself totally to the Divine, becoming a veritable embodiment of Divinity manifested in humanity."
