We destroy what we do not understand
It seems that since the edge stone we have always destroy the things that we do not understand, like witches, evil eye, "aliens", Library of Alexandria, Aztec, Maya.
It happens in society now days the envy and the jealousy.
We should be happy for other people happiness.
That will make a difference in our life, if we have a happy friend, we will have good energy from others good thoughts, and as well there will not be people that will envy our life.
We should try to understand others and not to destroy or envy their life.
