We are humans. A multi-dimensional creature that has all criteria in it. We are kind and hospitable, we are able to have hatred and be isolated.
We are the combination of our behaviors, whether they are good or bad. So this means we need to pick some of them and let some go. There is no choice. We are always in dilemma of picking up and letting go.
Neither hatred nor anger is bad. All of these are required sensations for well being and if not taken under supervision, will make us fail. Fail in our relation with people, our programs in the life, what we want to reach. Well, what do you expect you should reach? Which dimension of your life should be your life's leader guide?
