Sunna came up (ha) for the first time here just about two months ago, on July 5th. She is the Germanic Goddess of the Sun; Her Norse equivalent is named Sól. Both names just mean 'Sun.'
Sunna's sister is one Sinthgunt (Who may be a star Goddess, or a doubling of Sunna Herself), about Whom not a whole lot is known; in one of the so-called Merseburg Incantations, dating from the 9th or 10th century CE, both sing charms to cure Baldar's horse, which had become lame.
In Norse myth, Sól, the Sun, was created from the brightest ember that had escaped from Muspellsheim, the land of fire to the south. She was set in a chariot, drawn by two horses called Árvakr ('The Early-waking One') and Alsvin or Alsviðr ('The Fleet One'), which She drives across the sky every day, pursued by a wolf named Sköll ('Treachery'). She is said to be the wife of Glenr ('Opening in the Clouds').
An alternate myth says that Sól and Her brother Máni (the Moon), were originally the mortal children of a man named Mundilfäri ('Travels Like a Pendulum', perhaps an alternate name for the Moon), who were so radiantly beautiful that Mundilfäri named them for the heavenly lights. The Gods, however, were angered by Mundilfäri's hubris, and so snatched the children away, tasking them with driving the chariots of the Sun and Moon.
Sól is sometimes called Álfröðull, meaning 'Elf Disk', though this term is equally applied to Her chariot which holds the Sun.
I am glad to see Her after all the black of last week's Kali, I'll admit. Though I can't help but think the two are connected, as They are so markedly opposite. One week it's black as the Void and then the next it's the brightest of the Lights there are? Something's going on. I don't know if it's both/and or an either/or, though. The latter sounds like it could cause some serious whiplash. Take it gently, if that option resonates with you.
If the former, know that the digging in the dark from last week will allow you to stand more firmly, and be more grounded and rooted in the earth, which will form a stable base from which to reach towards the Sun.
Sunna is a healer, too; bask in Her warmth, and cultivate a sunny outlook if you can. It will help immensely at this time.
What does She say?
I am Healer, I am Light, I am the Sun, the Day-Star; I fly across the sky, regulating time, marking the day, and cutting the night up into manageable pieces, so there is never too much dark. Follow my example. Cut your darknesses up; make them into small things, and take them one night at a time. And do not despair. I am ever followed by the Wolf; yet, I do not let him catch me. Not yet, anyway. We will all be caught some day, it is true; in the mean-time, blaze forth in glory.
