What is the esoteric symbolism of the Swan?

Answer from the V.M. Samael Aun Weor.

Leda's swan reminds us of the charms of love. The swan of love makes the waters of life fertile. The fire of love makes life spring from the great ocean. Water is the habitat of fire. The sexual fire sleeps in the pure waters of life. Fire and water united in a trance of love gave rise to the entire Universe. Within our seminal waters breathes the fire of love. The fire of love makes the waters of life fertile. The swan symbolizes love. The swan only feeds on love. When one of the couple dies, the other succumbs to sadness.

Despite all these elements described, we still have much more; Just as the dove in Europe meant the Third Logos or Holy Spirit, the same was for the Mayans the majestic bird of the quetzal, the Egyptian sacred vulture and could not be less the swan as a symbol of this recondite energy. When studying the mysteries that this bird of paradise contains, we come across Greek mythology, in that precious story that tells us about the very origin of the universe and at the same time the key to achieving our intimate self-realization of the Being, enclosed in symbols, to that, as the master Jesus says: “for those who have eyes to see, let them see”.

Among the Persians it was taught that it should never be allowed to extinguish the fire (of love) in the altars (of the hearth), this same teaching is observed in the cult of the goddess of the fire of the hearth (the goddess Vesta) and in a parallel way in the Ancient Mexico we find a cult practically the same with the goddess of the fire of the home called "The one who dwells in the house" (Chantico). In the Middle Ages we are told about the swan knights, custodians of the Grail, and one is filled with enthusiasm when learning about the values they try to achieve; but that is not in the past, in reality we can be swan knights or swan warriors, what we need is to set our lives on fire with the fire of love, that is the way.
