The act of eating is a service.

[Shin'Ar]

...if you burn down a house because you didn't like the way it ruined the look of your neighborhood, and someone died in that fire, whether or not you agreed with the decision doesn't change the fact that someone died because of that choice...

If I kill someone by accident, do I polarize in the negative ?

I'll explain myself more.

Is karma and polarity the same thing ?

I believe they are two different things.

Killing someone by accident may result in karma, but not necessarily in loss or gain of polarity.

Catch my drift ?

Not really Valtor, I admit to having great difficulty understanding this whole aspect of STs and polarity.

My definitions do not seem to meet with those of this community.

To me polarity is the natural design of the universe and not a path of either positive or negative. so I do not know what you mean by polarize to to the negative or gain polarity.

And my understanding of Karma would have nothing to do with polarity/duality.

someone being murdered and someone being killed accidentally are obviously two different matters so I really don't know what your comparison is.
