As humans in general we were born with the knowledge of good and evil (the mind), but we always tried to separate them. If we try to throw one or the other out of the picture, we lose that balance. In a way, Satan IS the mind. But if the mind is capable of both good and evil, then Satan is not all evil as people think tend to think. If Satan is the mind, then yes, that mind is very capable of manipulating energy and creating lies. But Satan is also the same mind which knows good. Satan has two faces in other words. Good and evil. By achieving stillness of mind, we find the perfect balance of both sides. When those sides are as one, we in a sense become the "Tree of Life". We realize our potential to be "creators" ourselves. In a way, when the mind is still, Satan becomes God. The two become ONE. In that Oneness, as it said in the bible, "God is Love". It is the power of creation. It is that power of "love" which brings the man and the woman together to to bring life into being.
It is weird, but interesting how even "God" can love Satan. It is our own lies created by the manipulation of our mind that separates them as two. They are actually One. I hope that makes sense. It is just my perspective, but maybe I have it wrong.
