Harmonia is the goddess of harmony and concord, and her sister is Eris, the goddess of discord, who actually got the three original goddesses to feud over the attention of Paris - Aphrodite, Hera and Athena. Her brother is Eros, the god of love, and her parents are the Goddess of Love, Aphrodite, and the God of War, Ares. We can see already that the Harmonia Instinct in women is the desire to find order and social harmony, and that this is a "sibling" of love itself, and is what is "born" of the romance created between masculinity (Ares) and femininity (Aphrodite.) It is the feminine instinct to solve problems, through pure love and harmony.
If only it were that simple. The Harmonia Instinct is also one of wisdom - that the way the world works cannot possibly always maintain harmony, but that it must instead be fought for. And no better a place to see this behavioral effect happen than in the tale of the marriage of Harmonia. That one must be on guard for disharmony and not be seduced into thinking that it is always to last.
Harmonia is known to have been given a fatal necklace she received on her wedding day. When the government of was given over to King Cadmus by Athena, the patron goddess of Athens, Zeus gave him Harmonia. King Cadmus presented the bride with a robe and necklace, however, this necklace, commonly referred to as the Necklace of Harmonia, brought misfortune to all who possessed it.
Numerous gods and goddesses would come into possession of this necklace, and every one of them would succumb to some tragic event. The necklace had brought mischief to all who had been in possession of it. And so whether we are seeing a woman make progress in the workplace, or the decidedly chaotic and at times, fragile state of marriage between such different creatures - one masculine, one feminine - the Harmonia Instinct reminds us that this is the pride and vitality that come from a woman wise enough to know that she must always be monitoring her happiness, even in marriage, and constantly make corrections to keep things happy for herself, and for those that she loves.
