Why does Neptune influence the magic of Love?

Answer from the V.M. Samael Aun Weor.

To regenerate oneself means to generate oneself anew, in other words, to recreate oneself, to recreate oneself anew. This matter about being born anew is an absolutely sexual problem. Neptune governs schools of regeneration; this planet has a cycle of 165 years. Such a cycle controls the periods of public and secret activities of these schools. The esotericism of the schools of regeneration is the Arcanum A.Z.F. The masters of these schools teach their disciples the science that allows them to dissolve their ego. It is necessary that the Being (which is not the ego) be born within us. Something old must die within the human being and something new must be born within. Regeneration signifies the creation of a new cosmos within us. This type of creation is possible only by working with the Lion of Fire. Uranus controls the chakras of the sexual glands, yet the schools of regeneration are Neptunian.

Answer from the Magazine "The Wisdom of the Being".

“Female and male together make the seed germinate. Let Neptune then prepare the required baths, after the male devours his snowy swan so that two lose and regain their lives, four winds will blow and the king, by fire, will be united with his beloved wife full of love.”

This wonderful key speaks of the magic of Love, where the sacred sex, as an invention of God, offers the couple, constituted in legitimate marriage, the ideal gym to fight to overcome desire and favor love, that is, to overcome themselves in their passions and weaknesses; in the fight between the spirit and the animal beast, also represented, all this, by beings like Pamina and Tamino in the opera, "Mozart's Enchanted Flute"; likewise by Kundry and Parsifal in "The Sacred Scenic Festival" from Richard Wagner's Parsifal; likewise, the drama of Salome and John the Baptist; the seductive Eve of Hebrew mythology and Adam; Magdalena and Jesus, etc., etc.

Woman and man, (using the swan, an enigmatic swan that leaves no wake in its swimming and wonderful emblem of the fire of love) wrapped in the mysteries of Neptune and faithful until death, must lose their life full of defects, to recover the rich spiritual life, purity in everything you do.
