satan = ignorance of spirit,darkness
darkness = lack of Light, not understanding the illusion of the material world and the false conception of you and I as not One
we are all full of this ignorance or else we would not allow one Brother to live on a trash heap in a cardboard box in India while the other Brother lives in a 50,000 sq ft house, has more cars than they can drive while blowing thousands on egotistical possesions and events ...
one day maybe we will all get it and live in peace, harmony and love ... just ain't gonna be that day any day soon... in the meantime say hello to your own satan, we all carry it around
