That's true. It is dead simple. It's founded on a singularity which is immeasurable, and essentially indescribable. That singularity then manifests as duality...which can be expressed in terms of vibratory movement (wave-forms of energy). We then observe the playing out of that duality in uncountable trillions of forms, events, energetic movements, phenonmena, material objects, etc.

In all of these observable things we find polarity, expressing duality.

Male-female, dark-light, up-down, left-right, within-without, postitive-negative, good-bad, winner-loser, and so on...

People then set about giving all kinds of fancy names to these examples of duality they see around them, fighting over whether their interpretation of it all is more valuable than the other guy's interpretation, and so. That's how they formed the religions, and the political systems, and the social customs, and so on.

It's all in-out-in-out like the surf, or your breath, or your heartbeat, or the act of sex.

That's simple all right. The person who sees meaning and intelligence behind that Universal simplicity sees life as a spiritual circumstance. The person who thinks it all "just happened somehow by natural laws", but for no conscious or purposeful reason, doesn't see it that way. I think that's what divides people like Wolfgang and me, Bill. I see a meaning behind it all, he sees a functioning mechanism without a meaning behind it all.

As for people killing people for spiritual reasons...naw...I don't think so. People kill people for religious reasons. There's a difference! And they also kill people for money, power, and a host of other reasons, needless to say...but they very seldom kill people for any reason that I would term "spiritual".
