Sometimes I feel some negative energy gathering up in my intestines, I think this can be due to repressed negative emotional energy concentrating there.
In order to purify myself I tried this and this seems to work:
1) Vibrate Algiz (in cycles of x15 per time)
2) Visualize many Algiz runes shapes in a stream of white light cleaning your gut for every vibration.
3) Feel the vibrations in your gut and intend those vibrations to clean you of negative energy.
4) I don't do this but after the cycles of 15 vibrations, you can make some affirmation like: "my gut (or sacral chakra or wherever you actually feel a stagnation of negative energy, for me is the gut and sometimes solar plexus) is completely clean of negative energy completely now and forever", (x 5 times or x7...you decide but for me this works without affirmation).
5) Repeat the cycles until you feel release in the gut or wherever you feel stagnation of bad energy.
Hope this helps!
