I don't think that you summoned a bandar as bandars tend to hate you. Bandars also don't typically reside within a person, rather, they either reside near the person until they are banished. It sounds to me like you created an egregore (a spirit servitor), or judging by its power, an Archtypal Image (more powerful and intelligent version). Usually it takes a group to make Archtypal Images, but this one rests in your solar plexus chakra when it isn't active. (IMG:

genius! (IMG:

Here's a description of what an Archetypal Image is by Konstantinos:
QUOTE
Intentionally Created Archetypal Images (Group Egregores): These
entities are deliberately brought into being by magical lodges to serve as
guardians or energy sources for specific magical workings. Group egregores
are allowed to exist as long as the lodge of their creation exists and
sometimes longer. The reason they do not become dangerous, like normal
egregores, lies in the method of their creation. Unlike the latter, group
egregores work with an energy current. When not actively working for a
magical goal, these beings exist within this current and do not wander
around the physical plane causing trouble. If a magician were to align
him or herself with a magical current by joining a lodge, then he or she
would be able to evoke and work with these beings. A solitary magician,
however, has to work with either egregores of his or her creation or with
archetypal images of the following type: (describes Unintentionally
Created Archetypal Images)
Your solar plexus is the energy stream that your egregore/Image exists in when inactive. Normally this is somewhere in the astral plane, but the energy inside one of your chakras is sufficient to keep it at bay. I've never heard of this before! This is quite exciting for me. Well... there are dangers of letting egregores live too long, especially since it lives inside you, but the advantages are enormous. If it starts getting
too out of hand, then I'd destroy it and make another, but it sounds to me like you don't need to do this right now, especially since it's getting calmer.
The reason it's getting calmer is probably because you are working with an effective system of magick. I don't think it matters if you work with the Necronomicon, Solomonic Magick, Psionics, etc. as long as you practice magick. Being a magician grants you better control, and it increases your power.
