Emotions play a huge role in Runic workings. They can make all the difference between success and failure. Control of emotions is a valuable lesson for all vitkis.
For example several years ago I learned the hard way that too much emotion can taint a reading. I do readings for myself frequently. I had an issue come up that had me all over the place emotionally. I grabbed my runes to do a reading on the subject at hand. I didn’t bother to ground or center myself. I just dove in. And surprise surprise. In a nine rune spread seven of the runes were murk staves. A very negative reading. Which just caused my emotions to crank up even more. Cursing the gods I went to bed in a real state.
The next day I had calmed down. I was not emotionally revved up about the issue of the night before. I decided to do another reading. And what a shock! The results were much more positive. I took the time to center and ground myself. I was not emotionally involved. I was able to be a clear channel. Lesson learned.
On the flip side to do magical workings you want emotions. Excitement. Joy. Lots of powerful positive energy to send your intention into the multiverse. Without strong emotions behind it your sending will just be a whimper. Not at all conducive to changing the world you know. Strong positive emotions will carry the day.
So you need to keep control of your emotions if you want to do effective work. Both a lot of emotion or none at all depending on your desired outcome. But always you must be centered and grounded. Just one of the keys to powerful work!
